I don't think about delisting all of sudden. still regulators are not even near to making some first hand decisions. Then how come they are start acting upon privacy coins?
Regulators are not the same all over the world. This FATF is also not accepted by all countries.
It's obvious not all cryptocurrencies will want to obey the rules but that doesn't mean they'll be banned from every place. There's a market for privacy coins and even if some pussy countries like Korea ban them there will be plenty of other countries that won't.
