I agree in principle I think you could (I'm not a lawyer). However, you run into the starting problem of needing a trusted authority to verify a rights holder is in fact the rights holder. Also if the right is exclusive, how is that managed, i.e. prevent them issuing the same rights to many people. All answers thus far seem to point back to a central authority, and then what's the point of it being on blockchain.

Again, this is a different problem. One can imagine a service with a seignorage fee to verify such things when an NFT is minted after which that particular question is settled. The point of it being on a blockchain would then be subsequent ease of sale, transfer etc.

That's a gross simplification I think.

By service, I think you mean company, now I have to trust said company, also I need to check NFT is minted by company I trust, and that I trust the identifier of said company on the NFT. Now if it turns out the company wasn't doing a good job, what happens then, do the NFT's get revoked, by whom, what are the remedies and the compensation process?

All this gets bumped off chain fairly quickly with a hand wave whenever discussed, which quickly puts the block chain solution into question. If the NFT only works when minted and managed by trusted party, then is what we really need is data interoperability rather than blockchain. And even there, NFT's don't actually contain any on-chain or off-chain data expressing what the semantics of the NFT is.

> It's one for a legal-crypto startup but you can imagine selling some NFT being linked to a contract for transfer of copyright. Maybe nobody is doing this, idk, but they could.

What's to stop the buyer unbundling the property which is worth something (the copyright) from the pointless NFT?
