I don't see how this differs from a physical good in this way, say I don't like your price so I'm just going to take it can be applied to anything. I think if piracy was completely stamped out people may be willing to pay a price point that they previously wouldn't have.
Physical goods have a higher perceived value because you can touch and resell it. PC games are on their way to essentially ending piracy with services like Steam. Some people may be willing to pay a higher price point, but games at discounted prices are still tremendously popular.
