The argument isn't whether the person has a right to play the game, it's whether they would've bought it under any circumstances. That's what a lost sale is. If the customer would've pirated it or not bought it, it's not a lost sale. It's only a lost sale if someone who was willing to pay pirates it instead.
And who is to decide what they would not have bought? It can't be that they aren't interested in the game, because just by pirating it proves that they are. It can't be because of lack of cash because games go on sale all the time, for really cheap too.
It's such a stupid argument that you're throwing out there. I mean, at least the cheap-asses have an excuse if they miss out on the big sale. Saying you're not interested in playing a game then going out and pirating it is such backwards logic that it hurts my brain trying to understand it.

In other news, Valve is a pretty f***ing terrible company, let's be honest.
