If that's is all it took to destroy a cryptocurrency Bitcoin would be in big trouble. Gov could just say "Bitcoin is banned from exchanges" and it's dead. I'm sure you don't believe that though do you.
Monero was already delisted from the largest exchange in the world - Binance - a month ago and is already back around average price again.
You can swap any major crypto from any exchange for Monero. Literally one extra step. It's unstoppable.
