So you open a pool in El Salvador. they say fuck you BTC is our currency we accept all transactions..
A usa mine would be banned from that pool.
Or would they mine to a proxy via tor. And let all coins sit in a virgin wallet address.
If anything smaller miners will be nimble and the big mines could suffer.
or Donald mother-fucking Trump gets in and the gov goes in another direction.
That would work for time being. But for U.S. miners, they have to hope government won't create new law which prevent them from doing that.

You missed OP's point. He emphasize about U.S. government idea not to build block on top of block which include blacklisted TX/address which possible if 51% hashrate comply with U.S. government idea.
