If the passes were all registered as they were sold I don't see why Goldenvoice couldn't use something like Ticketmaster's system where you can resell a ticket to a show you bought except it's all verified by their system so you know you're not getting ripped off. But in TM's case it's like an ebay auction, whereas Coachella could just let you put your wristband's ID back into the system available for purchase anew at face value from GV and when it's sold just deactivate your wristband and refund you your ticket costs minus all the fees and whatever a fair fee is for "restocking" so to speak. You get a guaranteed ticket but if you can't go you can only get half your money back. I'd do it.
