This industry can only exist because labels and artists are not willing to sell tickets at the market clearing price, since they would be seen as exploitative by their own fans. So they sell the tickets are significantly discounted prices, in the hopes that at least some of them end up in the hands of the fans, saving face but creating a niche for a super-sleazy industry.

The solution I believe is to directly engage the fans and include with the price of the ticket benefits that only have value for fans. For example, when purchasing a ticket the market price is $100, out of which $40 is the price of the ticket and $60 is the "anti-scalping deposit" that fans get back when purchasing from their account with the band's site. So you would get $60 back in your account that you can use to purchase items valuable for fans such as limited edition CD, merchandise or even other tickets in the future (this is a bit tricky since scalpers can automate it, but exposes them to a major risk of detection and loosing the deposit, unlike the automation of the single ticket purchase, which either works or is risk free).

Providing this service seems like a nice idea to build a company on.
