But again, why do that if you can also bind tickets to names and use that to make yourself the only possible place where people can sell their tickets on, with a substantial fee (like Ticketmaster does)?

They have no incentive to let people freely sell tickets when thy can also force themselves in as mandatory man in the middle.

You can't cap resale prices with technological limits because payment can be split between multiple channels before the seller transfers ownership.

I could see that being a use case if it weren't for how much the underlying technology sucks ass. Blockchains spend too much time doing their silly little trust-less security nonsense dance to be able to perform at the scale needed by systems that will sell...say...Taylor Swift concert tickets.
