I think that the (biggest) problem with NFTs is that they grant no rights that are recognized by the governments of the world - the people who can help enforce your ownership. Worse, they require no rights to create. You don't have to be a copyright holder to create an NFT, you just need a URI. Your ownership of an NFT implies nothing about your ownership of the referenced object in real life (physical or digital).
