I reject this line of thinking completely. It leads to artists concentrating on monetizing existing art rather than creating new art. That's bad for society. Furthermore, live performances? Really? So that guy that creates an amazing piece by himself using Garage Band or whatever, but can't perform it live: he's just screwed?

And it's also just bullshit logic. It's the equivalent of saying that photographers should give up getting a decent commission on their photographs, and instead concentrate on selling champagne at a high mark-up at their gallery exhibits.
