So they get legal ownership of the artwork the NFT points to? Wait, what do you mean they don't? What do you mean all they get is a legally unenforceable digital hash representing that they "own" it in some nebulous way? What do you mean the actual owner of the art can mint a million NFTs pointing to the same piece of art and sell them all? What do you mean someone who isn't even the actual owner of the art can mint an NFT for it and sell it?
But it seems to me you just don't like NFTs. Most people who buy them know exactly what all this is about. If NFTs were "deceptive" in some ways (and of course there are always projects with 10K bot followers that aren't legit),then I'd agree with you. But I think for NFT people, it is what it is.
This deal is getting worse all the time!
