As your first argument - of course some people won't pay. However if they like it they will spread it to their friends thus helping find more people who will actually pay. On the other hand, how much money do those companies need to earn? They have way more money that they can spend, many workers are still underpaid or they just move production to India. Either way I still don't think its such a big problem. Besides nowhere is written game designers have to earn billions of dollars - why the heck should they? Do they do something else than other types of people working in different branges? For instance if food industry collapsed we would all die from hunger, yet they earn less then your average IT guy. Why? (Huge philosophic discussion threat!)
Those people who are really about restricting net have more money than whole america can put together. Money is just a tool but the tool itself is worthless and the wise are aware of that. However people are willing to give their whole lives just in exchange for some money (often dont have a choice). We need money to survive, they need us to shut up and keep working. I really don't think they care about money all that much, only idiots do.
