Privacy coins like Monero will be banned but privacy tokens like 0xMonero cannot be banned because they exist as assets on Ethereum and don't need to be traded on centralized exchanges.
But similar to tx from Tornado Cash, gov could force exchanges to orphan new ETH blocks that contain 0xMonero transactions. Since the grand majority of ETH mining nodes are on CEX it is not that far fetched.

They banned a smart contract ! Newly mined blocks could be just around the corner
On the other hand Monero will live forever ! It's market value will suffer but the gov understood it cannot be stopped !
