NFTs are nothing but a new way to record ownership. It does fuck all about the actual thing it is about.
I could use NFTs to sell my copy of Star Wars to another person. But doing so wouldn’t mean that I actually lose my copy of Star Wars. And neither would it mean that the other person gains a copy of Star Wars. NFTs are not better than a piece of paper recording a sale.
And there are far cheaper ways of recording a sale.
