Even your own health and well-being is not entirely you. Whatever you do to yourself has ripple effects on society. You go without health insurance, but when you fall ill or die prematurely, who takes care of your dependants?
Or more to the point, you sign up for Griddy and turn off your main breaker because the price went too high, then your pipes freeze and damage neighbouring properties or even worse, you freeze to death or die from carbon monoxide poisoning.
No man is truly an island.
