Overview
In this episode of *Hyper Entrepreneurship Radio*, hosts Kazuhiro Obara (IT critic and former McKinsey/Google/Recruit executive) and Kensuu (serial entrepreneur and CEO of Aru Inc.) dissect Facebook's audacious 2019 attempt to create a global digital currency called Libra. They frame the episode around a central paradox: Facebook, having become the world's largest digital nation with over 2.5 billion users, tried to solve a real problem—the 1.7 billion people worldwide without access to banking or credit cards—by building a borderless currency, only to be crushed within hours by a global backlash from governments. The conversation moves from the technical and economic rationale for Libra, through the concept of seigniorage and why nations guard currency issuance so fiercely, to the messy aftermath and the quieter, decentralized ways the same vision is being realized today. The tone is conversational, with Obara driving the narrative and Kensuu offering sharp, grounded reactions.

The Cambridge Analytica Prelude and Facebook as a Digital Nation
The episode opens by connecting back to the previous discussion on the Cambridge Analytica scandal, which occurred in 2016. Obara notes that 2016 was the year Facebook's user base surpassed 1.7 billion people—a number that exceeded the populations of both China and India at the time. For Obara, this was a personal watershed moment: it convinced him that he no longer needed to live in Japan. He relocated to Singapore and Bali because, as he puts it, "if I live on Facebook, it doesn't matter where I live in the world." This framing sets up the core tension of the episode: Facebook had become the world's largest "country" by population, and with that scale came both unprecedented capability and unprecedented threat perception from actual nation-states.
The hosts then pivot to the central case study: Facebook's attempt to create a global digital currency. Obara describes it as the inverse of the Cambridge Analytica story—instead of a platform being abused by a third party, this was Facebook trying to use its platform power for what it saw as a positive purpose, only to be "completely beaten down" by global regulatory and political forces.

The Libra Proposal: Structure, Partners, and the Basket Approach
Obara explains that Facebook announced Libra in June 2019, but the project was not a solo venture. To preempt concerns about monopolistic control, Facebook assembled a consortium of 28 founding members, each contributing approximately $10 million (about 1 billion yen at the time). The initial members included Visa, Mastercard, PayPal, Stripe, eBay, Spotify, Uber, and Vodafone—a mix of payment infrastructure giants, e-commerce platforms, and mobile network operators.
The currency itself was designed to avoid the volatility that plagues cryptocurrencies like Bitcoin. Instead of being a purely independent digital asset, Libra was to be a "basket currency" pegged to a weighted mix of major national currencies—the US dollar, euro, British pound, Japanese yen, and Singapore dollar. This meant Libra's value would be stable because it was backed by a diversified reserve of real-world currencies. Obara emphasizes that Facebook spent about two years preparing this structure, trying to anticipate every objection. The message was: "We're not creating some weird currency; we're just making existing money work better digitally."

The Immediate Backlash: EU Response and the Exodus of Partners
Despite all the preparation, the backlash was instantaneous and brutal. Obara recounts that within hours of the announcement, the European Union declared it would never approve such a project. The hosts marvel at the speed—"That's fast. Poor Facebook," Kensuu remarks.
Obara then describes the cascade of defections. Facebook's representatives tried to argue that if they didn't act, China would—pointing to China's existing diaspora networks (the "xiajing" or overseas Chinese communities) and the fact that China was already developing its own digital yuan. But this argument failed to sway regulators. One by one, the consortium partners withdrew: PayPal left first, then eBay, then Mastercard, Stripe, and Visa. Kensuu observes that the core problem was intuitive: "When a platform with that many users creates something like a currency, the sheer influence is terrifying." Obara agrees and uses this moment to introduce the key economic concept behind the resistance.

Seigniorage: Why Currency Issuance Is a Sovereign Power
The hosts dig into the fundamental reason governments reacted so strongly: seigniorage. Obara explains that in the era of the gold standard, a coin's face value matched its material value—you could melt a gold coin and sell the gold for the same amount. But modern fiat currency is different. A 10,000 yen banknote costs perhaps 500 yen to produce. The difference—9,500 yen—is profit for the state. This is seigniorage: the profit from issuing currency.
If Libra gained widespread adoption, that profit would shift from governments to Facebook. Worse, if half of a nation's money supply became Libra, the government would lose control over its own economy. Kensuu adds that this is not just about profit but about macroeconomic management: countries can influence their exchange rates by increasing or decreasing the money supply. The US dollar's status as the world's primary reserve currency gives the United States enormous structural power—what Obara calls "the strength of the anchor currency." Libra threatened to bypass that entire system.

The Deeper Threat: Libra as a Gateway to Total Platform Control
The conversation then broadens to consider what Libra could have enabled beyond just payments. Obara argues that if Facebook controlled both the communication layer (WhatsApp, Messenger, Instagram) and the transaction layer (Libra), it could become the intermediary for all cross-border work and commerce. With 1.7 billion unbanked people potentially using Libra as their first financial tool, and with Facebook already mediating their communications, the platform could effectively become the government-like infrastructure for a huge portion of humanity.
Kensuu connects this to broader trends: the rise of remote work, AI-powered real-time translation that eliminates language barriers, and the metaverse. He notes that "virtual earning" is already happening—Japanese creators sell NFTs to American buyers, settled instantly in Ethereum. The current banking system, by contrast, takes two days for international transfers and charges 2-3% fees. Libra was designed to solve this friction, but the very solution threatened to concentrate too much power in one company. Obara summarizes the dilemma: "The flow of the times says this is inevitable, but the question is whether a single corporation should lead it."

The Aftermath: Concessions, Failure, and the Quiet Resurrection
Facing overwhelming opposition, Facebook made a series of concessions. First, it abandoned the multi-currency basket and pegged Libra solely to the US dollar—a "dollar peg." Second, it moved the project's legal base from Switzerland to the United States. Third, it renamed Libra to "Diem." But by then, the consortium had collapsed, and the project had lost all credibility. Diem was eventually shut down entirely.
However, Obara and Kensuu argue that the story does not end there. The open-source code and development libraries created for Libra were released publicly and have been adopted by numerous Web3 projects. The vision of a global, frictionless digital currency is being realized in a more decentralized, less threatening way. Kensuu points to Telegram's TON (The Open Network) and LINE's Kaia blockchain in Japan as examples of messaging apps building their own cryptocurrency ecosystems. More importantly, stablecoins like USDC are already being used for cross-border payments, and services like WhatsApp Pay in Africa allow users to pool money and transact without traditional bank accounts. The hosts note that in Southeast Asia, ride-hailing app Grab operates a closed-loop point system where drivers pre-load cash and transact in Grab points—a de facto private currency that already exists.

Lessons for the Future: Decentralization, Open Source, and Patience
The hosts draw a broader lesson from the Libra saga. Obara argues that the failure was not about the idea being wrong but about the approach being too aggressive and centralized. The key insight is to "separate the layers"—no single company should control the communication layer, the transaction layer, and the identity layer simultaneously. By open-sourcing the technology and allowing multiple projects to build on it, the same goal can be achieved without triggering the same allergic reaction from governments.
Kensuu reflects that many people now think of Libra as a "big failure," but the reality is more nuanced. The underlying need—a fast, cheap, borderless payment system for the unbanked and for small businesses—is still there, and it is being met piece by piece through decentralized efforts. Obara concludes that the episode's real lesson is about timing and form: "If you rush too much, you cause allergic reactions. But if you distribute the change and let it happen quietly, it works." The hosts emphasize that this is not about giving up on ambitious ideas but about being "flexible" in how they are built.

Conclusion
This episode matters because it uses the Libra story to illuminate a fundamental tension of the 21st century: the collision between global digital platforms and the nation-state system built on territorial sovereignty. The hosts do not take sides—they acknowledge both the genuine utility of a global digital currency and the legitimate fears of governments losing control over monetary policy, financial crime prevention, and economic stability. What stays with the listener is the idea that Libra was not a failure of vision but a failure of execution and politics. The same future is arriving anyway, but through smaller, decentralized, and less confrontational channels. The episode is a masterclass in understanding why good ideas fail when they threaten entrenched power structures—and how those ideas can still win by changing their shape.

Key Takeaways
- Facebook's Libra (announced June 2019) aimed to create a global digital currency backed by a basket of major national currencies, targeting the 1.7 billion people without bank accounts or credit cards.
- The project was structured as a consortium of 28 companies (including Visa, Mastercard, PayPal, Uber, and Spotify), each investing ~$10 million, to avoid the appearance of Facebook monopolizing the system.
- Within hours of the announcement, the EU rejected the project, and partner companies began defecting under regulatory pressure, eventually killing the initiative.
- The core reason for government resistance is seigniorage—the profit and power that come from issuing currency—which Libra would have transferred from states to Facebook.
- Facebook made three major concessions (dollar peg, moving headquarters to the US, renaming to Diem) but could not save the project; it was ultimately shut down.
- Despite the failure, Libra's open-source code lives on in many Web3 projects, and the same vision is being realized through decentralized stablecoins (USDC), messaging-app-based currencies (TON, Kaia), and informal point systems (Grab, WhatsApp Pay).
- The key lesson is that ambitious platform-level changes must be decentralized, gradual, and open-source to avoid triggering political backlash—"separate the layers" and let the ecosystem build the future.
