How did I change the goalpost? Just because I refuse to let you dictate my position on it doesn't change anything. Although to be fair, it was others trying to dictate my position more so than you. An unregulated private market is rarely better than a guided private market. The private market is terrible for many things, like providing health care and education to the people. It also sucks for providing transportation, at least on its own.
The bottom line is, the private market always goes for the cheapest path and the one that presents the greatest profit. Always. And they don't care who gets trampled over in their pursuit of profit. Without assistance and urging, companies would not be investing the time and money into switching to electric power. If your idea of "companies will do this naturally" worked even the slightest bit, we would be able to travel high speed rail lines from Los Angeles to New York today. But because of the massive costs required to start it, the private market isn't making it happen. Well, that and a healthy dose of bribery from the airline industries and car manufacturers to keep it from happening (Oh look! The private market standing in the way of progress again).
Of course, you will read this and take it to mean that I think there shouldn't be any private market and the government should do everything, which is not even close to the truth. We need a system where the private market is allowed to do it's thing, but within a ruleset provided by the government and with the government occasionally guiding the direction the private market goes, based on our national interests.
