Coinjoin, if is done in a decentralized way, CANNOT be banned. Only centralized things / processes can be banned.

What they refer as being "banned" is when you use a centralized exchange. So stop using those. Stop using exchanges at all! EARN bitcoin, don't buy it anymore.

NOTHING that is decentralized can be banned or stopped. Stop living in fear. Buy, earn, spend, hodl BTC as you can and FUCK ALL THE GOVS.
