>I own several NFTs that are important to me, and they're worth every penny I paid.

The problem with the NFTs is that you don't actually own the art they represent and have zero copyright claim to them. In the absolute very best of cases, if you squint hard enough, you could see them as roughly equivalent to the signature of the original creator of the work of art and you're effectively buying a signed digital print of the work. In the worst and more common cases, you're buying nothing at all except a hash on a blockchain.
