> Who is this "we" you speak of? The energy is being paid for and the market demand demonstrates that it is a good use.

This argument is nothing but an appeal to the majority. I could equivalently say that the existence of spam emails shows that spam emails are good for society. After all, spammers have paid for the electricity and bandwidth to send spam, and the market demand demonstrates that it is a good use.

Market demand is a useful tool for measuring the current state, not for predicting an ideal state.
