I'm very interested to see what that kind of competition would do to ticket prices. I've often seen Ticketmaster painted as the "designated fall-guy" for consumers to hate instead of the venues and acts which are (according to this argument) the source of a lot of the junk fees. This is also the position that Ticketmaster claims as a defense [1], so it's hard to know what to believe in the absence of competition.
