I think NFTs probably have future utility in terms of proving ownership of physical assets such as property, vehicles, etc., maybe even for trademarks and copyrights
As much as I'd love to be able to change ownership of my car without government approval, I don't think this is ever going to happen. What if someone loses their private key? Now they just pay
€32,60 and get new papers. If you can replace your "registration token" by a new one, it defeats the purpose of using a token. I can think of more problems: what if someone steals your token?
