All good points, I guess that is a risk regardless, with Nostr. Someone could take paid photos or content from other platforms and put them on Nostr for sale too.

This would at least get them in the spotlight on Nostr and you'd be relying on users on Nostr to pay the ppl they follow because they want them to thrive and keep posting content.

Certainly presents risk either way.

It also raises the bigger issue, what risks will relay operators face in the future. Will people try to DMCA takedown content from relay operators? It would be wack-a-mole, but doesn't mean some won't try.
