I have to say that I'd need more time in order to properly think through your argument right now, and I don't have such time at the moment.<p>But the first thing that comes to mind is that no, these people shouldn't be ignored. This feels like saying "the very big thieves are always gonna be thieves, lets not worry about that. Instead, lets focus on the occasional thieves".<p>You might argue that since the items are not being lost, that doesn't have an impact, but I digress. There is no way to tell what would really be the pirate's action were him totally prohibited from pirating. What would he do.. pay for the stuff he likes, turn to a new hobby? Sit still thinking about all the things he is not doing? We can't know.
