Re: Sell them like airline tickets
But that also harms genuine buyers. You have to buy these tickets 6~12 months in advance. So as a genuine buyer I could end up not being allowed in because I left my photo ID at home (not every country has to carry photo ID everywhere).
Also if I find that a month before the concert I can no longer go because my circumstances have changed then I may find it impossible to resell or pass my ticket on to a friend due to 2x-10x cost of doing so.
It's like DRM, it is designed to stop the bad guys but ends up just being a PITA for the good guys.
