This is a trivially solvable problem with essentially little friction for buyers.
The industry doesn't WANT to solve this. I don't see why anyone believes or entertains the idea they are even trying.

Situation 1: My co-workers could not get time off work, so I am asking my tennis buddies instead. I am transferring tickets to their names.
Situation 2: I am actually a scalper! I've got paid 10x times the price (via venmo), and I am transferring tickets to those random people.
How do you tell those 2 apart?
Scalpers can't transfer tickets in this system.
