Not sure about the first point, after all with digital art what matters is the NFT since anyone can copy the artifact 1:1 at virtually no cost and no risk. I agree with many that NFTs are best suited for digital worlds but that begs the question: what happens if the game is centralized? They can still prevent you from actually having or using that item, regardless of any proof of ownership.

Re: wash trading, that also happens in the art world with shell companies.

Use value is easy to assign to an NFT post-facto. That hasn't been really done in the current market(which is, of course, in the midst of a bubble), but:

* Tokens can become tickets to events

* Tokens can become options on commissioned work

* Tokens can become signs of membership

Because the token is guaranteed to be unique, and you can track ownership, there's a fluidity to this that lets you do away with contractual mechanisms. You can reuse the same tokens many times or announce that it will expire(for your use case).

Edit: And platforms can't really own it if it's on a public chain, too. You just copy the chain(see: BinancePunks copying CryptoPunks). So there's that.

What prevents people registering a new NFT for the same work? Provenance might not be easily justifiable purely by date it was created.
