i think #bitcoin would still be fine with the speculation / shared hallucination about it's value. if it could hang on to it's supply cap.
it would protect your purchasing power against real inflation, and it would provide an opt-out from the consequences of fiscal and monetary policy.
but bitcoin in a high -trust environment (white markets) loses all of it's cherished properties. including the scarcity! bitcoin only makes sense as a low-trust (supra-legal) system.
in the absence of large, liquid, established gray or black markets and circular economies that insist on final settlement on-chain and provide independent price discovery, at bifurcation the massive power advantage goes to the regulators and their enforcers, the financial institutions.
