For most of human history, the bread problem was solved by money. You hand the baker coins, the baker hands you bread, neither of you needs to know the other's name. Reputation only became necessary once we introduced asynchrony and reversibility: credit, chargebacks, pay-later. The seller has to bet on who you are instead of what you paid, and that bet is what accounts, KYC, fraud scoring, and social graphs are pricing. Identity theatre is unpriced credit risk in a uniform.
Cashu and Routstr collapse that detour. Bearer ecash for an LLM call is structurally identical to coins for bread. Settled on the spot, no counterparty bet, no recourse needed because there's nothing to recover. We didn't invent anything. We walked back to where we started after a few centuries of building ledgers, banks, and identity systems to patch the holes in deferred payment. Money → identity theatre → money.
The cypherpunk point here is boring: finality is cheaper than verification.

I’m bullish on innovations which refactor deranged civilizational structures.
Great point about how cash enables anonymous exchange, but I’d push back slightly—identity theater (KYC, social graphs) isn’t just about credit risk; it’s also about control. The rise of age verification laws, for example, shows how “trust” frameworks get weaponized for surveillance. Reminds me of this piece on the privacy trade-offs:

until the mint decides to invalidate those bearer notes
The mint can be run by the service. And you need convert Bitcoin to notes as you need, no need to go big. So this is a non issue for this use case.
