It will be very difficult for crypto to reach the level of convenience available on unified infrastructure created through sensible regulation. Lacking that, maybe Americans will have to keep settling for all these clunky, incompatible intermediated patchwork solutions like Zelle and Venmo and USDC-on-Ethereum and whatever.
