Using money, some people have far more than they need, and others do not have enough. Money prices by scarcity, and does not encourage energy efficient or sustainable actions by individuals or society with nature. Measuring the energy efficiency of actions, and the sustainability of those actions, is a rational way to judge performance of people with regard to each other and nature. It takes a village to raise a child - it should be a village decision how many children are born. The criteria for how many should be based on the balance of resources sustainably available.
Survival is of the fittest society, since no individual human is fit to survive.
Use of flawed measure of money for actions, makes for poor energy efficiency. Societies that insist on using it are engaged in mass irrationality, and will fail. Acceptance of rational measure gives the best chance for survival.
