I don't think people really understand how the entire world is a complete fiction. The idea of ownership is made up. Your house deed isn't a statement of ownership. It's a promise that if ever someone ever comes with a gun to take it from you, a larger group of people with guns will take it from them and give it back to you. The whole world is a fractal fiction invented by other people. NFTs like any other symbol of value depend on the collective social fiction.
