Imagine the president a hundred years ago when there were few cars and many horses and buggies. He decided horses were messy things that pooped everywhere and took up usable farmland for their feed rather than for human feed and that cars were much better. Of course, cars were extremely inefficient and expensive and there weren't nearly enough of them, but the president decided people needed to switch to cars anyway. He wanted to raise taxes on hay and horses and wagons and all things related to their use so high people couldn't afford them any more so that they would switch to cars. A hundred years ago, people would have said no way. It makes as much sense and our president wanting to tax fossil fuels and everything related to them so we would switch to solar and wind, which are expensive, inefficient and just not widely available.
