I agree with what Gecko said a few pages back: people that use 'warez' most likely weren't going to buy the product anyway, so the company doesn't technically lose anything.
Personally, in the future, I'd just like my music to be distributed, so I wouldn't mind people downloading. Of course that would probably be different if I worked at a software company or something. It would be a 2nd profession too, so as long as I'd have income I'd be cool with it; at least I think so, I know a lot of things can change when stuff gets financially rough.
I don't know, I'm an advocate of making music for people to hear it, not to pay me off. Maybe that's old school.
