I was being a little sarcastic, though if I had to name a few real world use cases for blockchain event ticketing would actually make some sense. Everyone hates Ticketmaster and resellers like Stubhub are rife with scammers. If you can build a solution using blockchain to reduce ticketing fees to 0 and enable ability to resell/transfer tickets it might work.
Decentalization could solve stuff in this space by having the actual event-holder selling the tickets and such.
Adding blockchain to it won't solve any problems that can't be solved traditionally better and easier.
