It is worse. Anyone can own it. NFTs don't avoid copying, and they are in no way recognized as copyrighted material. Its like having a proof of ownership of a public good: worthless.
I don't know what you're talking about.
I just bought the NFT for the SF Golden Gate bridge, which surely means I own it.
The fellow who sold it to me said so.
Instead, if there were only a few produced in the world, and you owning it give you some kind of status, then you'd have a real potential NFT.
