I'm not really for pirating, but I also don't think it's the same as breaking into someone's home and taking something or stealing a car. If you steal a car, the owner no longer has it. That is not the case with piracy.

A better comparison would be to say it is similar to having someone do something for you and not pay for it. Also a deplorable act, but not nearly as damaging as taking an item away from someone. You could argue that he is taking the programmers' time away from them, but I bet you they already got paid. You're really taking money away from the owners of the company, or at least postponing payment. =D Like I said, it's still wrong, just not stealing a car.
