That certainly works if everyone pays for stuff they like. In which case you could certainly extend this pricing out to most products. For example if I buy a meal at a restaurant I am only obliged to cover the direct costs incurred (and maybe something towards overheads) by the restaurant in providing me with that meal, any profit is discretionary.

I certainly do still see plenty of people who can afford a new car and a holiday every year pirating movies etc and still complaining if something sucks.
