yeah, i mean, that's kind of a new idea of attacking bitcoin is to try and make people criminals who build on top of a block that has a blacklisted address. since bitcoin is only pseudoanonymous, usa-based bitcoin miners would need to either build on the usa government's recommended chain or figure out a way to launder their BTC through monero or something so they don't get caught. i guess it all depend on how much hash power they could get under their control as to if bitcoin could survive that or would it split into 2 chains?
