Leroux: I'd rather say "market != representative democracy", so it's more likely to work if you're not in the minority. Your examples don't disprove that you can vote with your wallet, they only point out that the majority of gamers doesn't care that much and would rather play the game anyway, regardless of the DRM it's got.
It might not even be a democracy of the majority.
It's all about numbers: straightforward, single-minded mathematical optimization on the income - cost figures.
If they can make more money by selling at an outrageous price to fewer individuals than they can by selling at a reasonable price to many, they will do it.
In the case of games, it's not so bad, because you only buy a game once (ideally) and the competition is intense & uncooperative (so far), so they have to phase out the price overtime to get at those who wouldn't pay the initial release price, but it might not be so for other consumer products for a slew of reasons.
It is possible to charge sky high prices on vital or highly important goods or otherwise engineer an artificial scenario where people will crave badly for something and then make sure you charge them a lot for it.
Furthermore, a company will sometimes push their interests as far as customers will 'tolerate' it, but that doesn't make it democratic.
A customer might be willing to put up with an intrusive DRM scheme to get a game they really want (perhaps is a genuinely innovative and good game or perhaps it's just been hyped through the roof to generate a high artificial need for it), but that doesn't mean that they'd agree to have the DRM scheme on if they could vote on the matter.
And before you tell me that if they could vote on the matter, they'd vote to get the game for free and wouldn't make any money, I'd tell you the situation can be compared to balancing the budget of a country.
Yes, people would prefer not to pay any taxes and get everything handed to them by the government, but practical realities don't work that way.
So, they have to compromise with practical realities, but still vote to get as much as they can out of it.
Similarly, if the market was truly democratic, then the need for companies to make some profit would be recognized, but the ability of companies to push their interests too far would be kept in check by something a little stronger than just the customers having the option not to buy.
