I think the analogy to baseball cards works very well. Owning an NFT generally doesn't grant you copyrights over the underlying work of art. Owning a baseball card doesn't mean the athlete now works for you. They can both still have value as collectible items, if that's something that interests you.
The problem is when people start talking about NFTs as if it entitles the holder to ownership of the underlying thing. It's possible to own a work of art, either physically or in terms of copyrights. NFTs are neither.
When Dorsey sold an NFT of the first ever tweet, that didn't entitle the buyer to copyrights or even the ability to delete the tweet. It's purely a collectible that derives value from official endorsement and scarcity. That's not something that interests me personally, but it all seems above board. The problem is when I read Dorsey sold the first ever tweet. He did not. He sold an NFT.
