Good points, slayda. I certainly don't think people who don't read (or listen to music, or look at paintings) owe those content creators anything. They may choose to support the arts in a general way, on principle, but it's a very different situation than someone who enjoys the arts but feels no obligation to pay the artist.
What I was trying to get at is that I sometimes hear people justifying their behavior by railing against capitalism... which is fine, but working alternatives to capitalism all involve "paying back" by some other means. There's no free lunch, no matter what economic system you use. Not in the long run, anyway.
