This was actually the original idea of non-fungible tokens, but because you need special legislation to tie an object to this digital receipt (there is nothing legally tying one thing to the other), they just skipped over it completely and said the NFT itself was the commodity, which is why they could only do it for digital art with the a web link. (we could, for example, see this more useful for a title to a car or house)
In fact, many NFTs don’t even contain any language about copyright or licensing, they don’t even attempt to pretend that the NFT holder owns the copyright. The owner of the NFT in these cases only owns the NFT, and not the copyright. Of course, you have to transfer the copyright separately from transferring the NFT, which makes this whole thing redundant for buying/selling on secondary markets, but they could have at least tried to pretend they could.
