If you want to place downstream restrictions on your content then you have to license it (and get someone to agree to your license). You have rights over how you license content. Yes. And users may agree that they're only "viewing" a copy and don't in fact own it when engaging with your licensed content, sure. But my main point was that you don't get to publish content to the public domain and then say oh wait no I didn't want Meta to see that oops #privacy #cancelmeta. And further that it's kinda silly to imagine a world where everyone licenses every little toot they make. At some point we're in a public forum and we just all need to understand what that means, including that someone you don't like might be listening.
Anyway, I don't think licensing content is a positive thing for society. It may benefit media conglomerates, but not individuals. Arguably, creators shouldn't be allowed to say "Netflix you can stream this content to users but not in Brazil". I don't think it's a sealed deal that downstream restrictions on content distribution are healthy or in any way in the public interest. Charging a royalty for a views/streams of some show is one thing. Saying "only on Tuesdays and not in Brazil" gives too much control to creators to dictate how their art should be interpreted. And nobody can prevent you from using Netflix to stream a show to your Brazilian friend on the couch next to you... nor should they ever be able to. That would be really really bad technology, were it to exist.
So short of attaching licenses to every post you make, no, there's not a socially healthy, let alone even viable, strategy to control content distribution in the "fediverse".
