Usage-based pricing only discourages use at a certain level. Do we refrain from using telephones? Electricity? Water? Yet many of us pay for these, at least in part, on a usage basis. It's all a matter of pricing level, isn't it? The trick would be to work out a pricing model which, in total, produced the same amount of money (give or take) to producers, but distributed its payment more fairly among users. Of course, heavy users who paid more would hate it - low users who paid less would love it. And that may, in fact, be the main obstacle!
