I do not know the book.

I think it is very easy and cheap for the gov to surveil everybody. In only a few years you will have mandatory digital ID.

Then they only have to write a law into their magic book that only BTC transactions connected to a digital ID are legal. If you send to somebody without that, you commit a crime and they punish you for that.

People will comply. You saw that with the covid theater. People take a experimental gene therapy just to fit in and then try to force others to do the same.

If you store your wealth in BTC which they will know, or any other asset in the banking system, you can leave the country but they will take your stuff with an exit tax.
