People love to claim that NFTs can only be used for signed pictures of gorillas, but imo they are probably one of the most interesting utilities on a blockchain. Have you ever tried to buy a ticket through ticket master? It's not a wonderful experience.
Digital event tickets could be sold directly from the venue to the attendee without any of the hassle of TM. Tickets that are non-fungible (ie an assigned seat at an event) can be represented with NFTs. Fungible tickets (ie no assigned seats, maybe access to any event within a period) can be simply tokenized.
That isn't a use case that exists now, and because of the toxic association that the term "NFT" has, it probably won't exist. It's a shame though, because the technology exists, and works better than existing options.
