Well... not exactly on that "NFT" thing, copyright, and ownership. First block chain (meaning signed hash systems) have been in use since the 1980 for protecting property...try money in the form of ISO X.509 certificates. You hash something with the owners name and address and sign it. Your signature is verified by the signatures of others up the chain.

Now: what is protected in law established by the United Nations signatories is the "Object Identifier" which is usually a big number or number series (like a globally unique telephone number with a couple of prefixed standard numbers to say it is an object identifier of a certain kind). Also hashed into the hash protected by the certificate. This, which states the owner, is legally protected against impersonating the object identifier part under penalty of felony in most all countries of the world. (In fact, it protects against fraudulent use of telephone numbers).

and P.S. in the chip credit card in your wallet are more than one X.509 certificates certifying the movement of money by an entity, given by the object identifier, who knows the private key for the public one in the certificate (the chain of ownership or authenticity). Forgery is felony.

That said, who the hell knows what these NFTs are. If they are X.509s, there is law. What is clear is that NFTs, and block chains, are just copies of public key infrastructure (PKI) already well understood and in massive global use to protect the unique identity of things from digital copying (the ownership of a key that globally uniquely authenticates the corresponding public key and something with arbitrary bits also properly registered with copyright and owned). And there is international fraud law if those idiots only knew. But PKI was patented for many years, so people just stole it by other names.

There are tricks to give NFTs power to protect copy rights (as opposed to copyrights specifically). That said, I completely agree with your theme that this stuff is nevertheless (but I say needlessly) the stuff of lying grifters and poor suckers.

Just say'n.
