"NFT Art" is a stupid implementation of NFTs that probably mostly exists for money laundering.
I always thought of NFTs as a good backend for things like concert tickets or other kinds of "club memberships". This would not really have the enforceability problem, at least not more than traditional tickets, while some new features are added.
If someone is enforcing the NFTs then that someone could just as well store the data in some SQL table, since there is exactly 0 decentralisation in that case
But there is no way to prove that the issuer is actually the person who "owns" the event. This all goes back to the oracle problem: Unless the proof exists on-chain (like the currency value of a public key), it is useless; there is still an "oracle" outside the chain that must provide the proof.
This is why NFTs are not useful.
NFTs in their current hype cycle with art is a shallowly thought out implementation.
It requires a governing body to source the originals but then you essentially have a coin at this point.
