It would be great if the US could cut down on oil consumption, particularly for the environment, but again, we are discussing completely different economies. Being a net exporter would not have the same effect. I think it is unreasonable to compare $300 billion GDP countries with a $13000 billion GDP country.

The question is not an ideal, 'what it gains,' but whether it is practical. And it is not.

I agree that the Nordic countries have a good setup, but these countries are nowhere near the economic or physical size of the US. They also have oil resources which make a huge difference on a per capita basis.

It is a nice idea, but I think the application of these economic systems on the U.S. is complete fail... in this century anyway.
