Monero exists in a global market. There are many many exchanges all over the world. On top of that, Monero can be trivially exchanged for other cryptocurrencies without the use of custodial/permissioned exchanges. The cryptocurrency genie is out of its bottle.
Pure propaganda with no evidence. Major exchanges like Kraken are still trading it even in USA.
Even if it were banned it would have little long-term impact. Literally impossible to stop decentralized swaps unless they also cripple BTC. it would be very powerful actually for people to realise how unstoppable it is.
