Theoretically yes. Big pain in the ass though. Especially with anon accounts, who do you sue? The play would be to go after the aggregator level. Is Primal a target or Damus for facilitating an illegal marketplace? How hard/easy to go after them?
Another angle that would make it harder is if you do not explicitly charge a price. If you post it for free, and then subsequently a variety of folks zap you a variety of amounts are you really reselling it for profit?
I'd be curious what a legal pro would say as far as what constitutes selling, vs profiting from. Definitely the anonymity is a factor, though I could see a bored security agent lurking on someone long enough to bring chase to the client, the platform it came from, anything they could do. Governments don't take kindly to what they can't control it seems. I don't even know if they're capable with any of that but an interesting rabbit hole that I am sure is laced with assinign regulations.
If you really want to know the answer, try it at scale and find out. Stream a full Disney movie or something.
