What's the effective difference between "e-piracy" and a library? With either one, I can read a book and not have to pay for it. With either one, I can (and have!) discovered authors whose books I would not have if I'd had to pay first. And guess what? Some of those authors, I've gone and purchased some of their other books. Sales made that never would've happened had I not had the chance to read them on a trial basis.

I'm pretty sure that's not the issue you necessarily intended to address, but it's a starting point for realistic discussion on "the scourge of the artistic world known as e-piracy"... whether it's books, music, games, etc.
