The point is that costs should be applied fairly so that people will make decisions that are also rational at the system level. The system isn’t rational now so fixing that will change things. You can have principles or you can maintain the status quo but you can’t have both.

If your principle is everything should be cheap you’ll say you don’t want to pay taxes and the roads will go unmaintained and you’ll pay in accidents and delays and insurance and repairs. There’s no such thing as a free lunch.
