Banning was the first level thinking.

Forcing Bytedance to sell (ie confiscating), under a permission renting it to some of their stooges like Mnuchin, meanwhile openly threatening the rest about their destiny if they transgress is the second level.

Win win game for all their friends, lose lose for all their enemies.

No need for bans when you can squeeze the juice (ie fully KYC-ed Bitcoin surveilled with AI).
