I suppose if we're requiring showing ID to attend anyway, it's not a lot worse to add an online ID verification step in order to be allowed to be a "sender" in the transfer system, and an identity is only allowed to have like 5 distinct "friends" in a rolling 12-month window.
Part of me thinks that Ticketmaster/Live Nation probably makes so much money from their own in-house scalping operation that they don't want to fix any kind of scalping problems for fear they would be somehow obligated to not participate themselves.
