There's a level where the detachment from reality is fatal, for a person or for a country.
If you are all whacked out on LSD and decide you can fly off the top of a seven story building, you will die.
If you are hungry and decide that eating razor blades is a great idea, you will die.
If you believe you can force people off oil, with no reasonable alternative, and simultaneously lower the price of oil, your country will die.
