I have never, nor will I ever, buy a pdf. I've never accepted an illegal copy, but if I was to do so, it wouldn't hurt anyone. It would still be stealing, mind you.
That's just not true. Widespread illegal copying helps create an environment where people don't believe they have to pay for music/software/gaming books/etc. So the "buy threshhold" for many people is far higher than it would be if they didn't think it was "okay" to download something that they "had no intention of buying", even if they don't conciously realize it.
