In the email he sent announcing this ticketing system, Louis CK explained that he's making what he considers plenty of money, so he wants tickets to be inexpensive for his fans. They also have their system set up so that if they can tell that someone is scalping their tickets, they will refund the money and revoke the tickets. I agree with you in general, but Louis CK doesn't give a shit that he's leaving money on the table. He wants it to be easy for his fans to get to his shows.
