> Coincidentally, NFT’s got the “transfer” side of the equation, but forgot about the “privilege” part! The tokens are yours in perpetuity, and can be transferred to others, but it’s not at all clear what privilege they provide.
Exactly! This is the part that I cannot get past whenever people talk about NFTs. They are a neat toy, self-contained, and having unambiguous ownership of the NFT. But there is absolutely nothing in the real world connected to it. It's like those pie-in-the-sky physics models that have hundreds of free parameters unconstrained by any experimental measurement. Sure those models might make some interesting predictions, but they have nothing tying them to the real world.
I could imagine a system where NFTs are used to establish ownership, but that requires there to be some trusted source that signs the initial NFT. This could be a land surveyor to make a NFT that represents property borders, or a patent office to make a NFT that represents a granted patent, or a MMO video game company to make a NFT that represents a particular asset within the game. But as it is, J.K. Rowling could make a NFT representing "Harry Potter and the Philosopher's Stone", and I could make one as well. There's no indication of which one is a valid link from mathematical space to real space.
NFTs need a legal system in order to tie them to anything outside of the NFT ecosystem. They need trusted authorities who are the only ones that can generate NFTs with specific legal authority. And once you have that trusted authority, there's no point in having any of the other trustless blockchain architecture whose sole, flimsy excuse for existing is in avoiding having a trusted authority in the first place.
(Sorry, that turned into a longer rant than I had expected, but your phrasing crystallized some ideas that had been floating around my head, and I wanted to write them out to see where they went.)
