And the REAL real problem is that the market will bare a lot. I once sold tickets for a Die Antwoord concert I couldn't attend due to illness. I advertised the tickets on Craigslist for $100 for both, the retail cost being $50 each.
But when I arrived at the venue to sell the tickets, the buyer put $200 in front of my face assuming I had meant $100 EACH. My greed got to me and I took the money.
My conclusion was, ticket buying is not rational, and the ticket market is extremely liquid, so without tying tickets to an identity like airline tickets there isn't a good solution.
