When you get a title from the real DMV, it's backed by a lot of mutually reinforcing real power. A group of kids can get together and play DMV, issuing titles to each other in crayon on notebook paper. In both cases there is only meaning by consensus, but NFTs sure seem much, much closer to the kids playing.

Everybody except a few conspiracy nuts believe a title is what it is supposed to be. Your friends and neighbors, your parents, the government, the courts, law enforcement, car dealers… but the only people who believe NFTs are what they are supposed to be are insiders.
