To be fair, me alone going vegan is not going to stop the meat from hitting the shelves.

We need global organisation and co-ordination to do this.

And in Germany every year there's articles that the slaughter factories can't sell as much as last year because people eat less meat. Yes, Regulation is needed and great and all but it won't happen if everyone is sitting on their ass still eating meat showing the world that they don't care about the slaughter factories. Individual people still make a slow difference and that's better than just yelling regulation while eating corpses.

By your logic we should all use LLMs because it's the big corpos that own the data centers so there's nothing you can do

Corporations aren’t just killing animals because it’s fun. They do it because you pay them for it.
