There is also not really a way to enforce a physical concert ticket, but with a NFT, the owner can prove ownership and authenticity of the ticket (for example when re-selling a ticket), without relying on collaboration of the issuer of the ticket. The issuer can show that they created a fixed number of tickets and are not over-selling the event.

>The issuer can show that they created a fixed number of tickets and are not over-selling the event. But there is no way to prove that the issuer is actually the person who "owns" the event. This all goes back to the oracle problem: Unless the proof exists on-chain (like the currency value of a public key), it is useless; there is still an "oracle" outside the chain that must provide the proof. This is why NFTs are not useful.
