Why buy it when you could get it for free? Just walk out of the store with it without paying, right?
I once heard a comedian talk about that. He was talking about those "anti-piracy" ads that are on dvd's now, where it says "you wouldn't steal this car, would you?", and the guy was like "if I could make an exact digital copy, leave the original untouched and with its original owner, then yes, I'd steal that car."
You can't get me to pay for something that doesn't physically exist. If you're buying a cd, that's one thing. That you can hold in your hand, throw, soak your feet in it, rub it on your chest etc. A digital file?
It doesn't really exist. It's virtual memory. It's not even close to stealing a product out of a store.
