It’s weird to keep using the Mona Lisa, when there’s a much more apropos metaphor intimately connected to crypto: NFTs are like naming rights.
Crypto.com did not buy the Staples Center, and doesn’t have the right to charge admission. They bought (leased, really) the right to have their name associated with it. Some of that has the force of law, but a lot of it is social convention too. Here in Chicago, the Willis Group owns the legal naming rights to a large building downtown, the building itself is owned by Blackstone, and locals actually call it the Sears Tower.
