I assume you're excluding psychological harm since that's not objective, so it would have to be financial, and there is no research data to prove that pirates harm digital sales of any digital media (since there's no comparison).
Though, I don't think harm is the only metric for doing something wrong (or right). If you can steal somebody elses work, knowing that they don't want you to, are you justified in doing so anyways just because they can duplicate it?
i mean even psychological harm doesn't occur since you never know when someone else has pirated your game.
what other metric would there be? what's another example of something you can do that hurts nobody but is still wrong?
you would not be justified in stealing someone else's work because they lose that piece of their property. they may be able to duplicate it to replace it, but they shouldn't have to. that's not what happens in piracy though, you don't lose any property and you don't have to duplicate anything to replace anything.
