Perhaps there's some tiny little caveat, like "well, it does screw up artists who only want to do electronic distribution, and who don't tour" or something.
The point I'm making is if we just argue our own points to the point of utter conviction, we lose the power of being able to see it from both sides.
Take a look at the whole problem; take a look at all the different players (labels, artists, listeners, isp's, services...)
Take a look at the whole situation.
