You know what is called when you dress warmer indoors because heating is too expensive, and when you don't shower so often to save even more energy?
Poverty. It is what we did when the world was much poorer.
Just because a behaviour is associated with poverty doesn't make it incorrect, nor does it make the opposite behaviour correct.
For example eating less is also associated with poverty. But people in more economically developed countries eat a massive excess of food causing epidemics of obesity, diabetes, and heart disease. Just because eating less is associated with poverty doesn't change the fact that eating less would hugely benefit the health of most people in wealthier countries.
Sometimes affluence results in excesses with significant negative consequences. And our excessive diets and energy consumption both have significant negative consequences.
