What about the lightning network? Or Liquid sidechain? There are lots of people working on scaling bitcoin so that it can be used like cash (low fees and anonymous).

When a user receives a payment in Cash App or Strike over the lightning network there is no way to track where that bitcoin came from. I haven't really tested that out yet, but I find the idea that bitcoin can be the rails of transferring value pretty compelling. Most people can still transact in fiat but with trustless interoperability between banks and service providers. And of course if people are happy transacting in units of bitcoin it can all be done in a trust-minimized way (with tradeoffs available for convenience, etc...).

But to your point, the government could crack down on the app stores and service providers to not support this kinda stuff.
