>I’ve come to the conclusion the only way to make progress on carbon is to ban the sale of new devices that use fossil fuel when an alternative technology exists. Maybe if you're a dictator.

That's kinda besides the point. The point is that without some kind of ban (viable or not, political opposition or not, made by a dictator or made by public voting, yadda yadda), you're not likely to make progress on reducing carbon emissions.
What's wrong with something like a carbon tax, which lets the market decide what the most cost effective way of cutting carbon emissions is?
