I think of government as a relatively recent adaptation for our some of our species’ less socially-harmonious impulses. Government makes formal our ability to gather in groups and come to a shared understanding, across diverse and often contradictory belief systems. Humans have always been really good at this, but modern governments and their accompanying bureaucracies take it to the next level. Sure we lose some efficiency, but that’s what happens when you’ve got massive populations.
I believe government is meant to take the place of the caretakers of old who would have been responsible for the well-being of the group. If you think of government as an extension of ourselves, the part that cares for the collective for the benefit of the individual, and vice versa, then it’s one of the most critical components of our survival as a species.
Ideally, government should provide everything that an individual cannot provide for themselves. If a person isn’t a builder, then government should provide a place to live. If a person isn’t a farmer, then government should provide enough food to survive on. If a person isn’t a doctor, then the government should provide medical care. And so on. All the essentials we need to live should be provided by the government, because the government is us.
