A better analogy would be that the blockchain is a filing cabinet. A deed has the force of law because the city/state is prepared to use violence to enforce the ownership claim inscribed on the deed. What authority is going to enforce your NFT?
When twitter integrates NFTs and requires you to sign a proof of ownership to set an NFT as a profile picture (with a verification check mark), this effectively signals that twitter is enforcing the NFT. When facebook does the same, it signals that Facebook is enforcing the NFT. When Spotify integrates NFT licensing, they will be enforcing it.
