I'm talking about necessary for the species to carry on existing. And yes I grew up in a place with no police, no military, no EMTs, no firefighters. We had a nurse though. If someone did something that would normally involve the police, it was settled by the parties involved. (If you got drunk and drove through someone's fence, they'd show you up at your house with a roll of barbed wire and some fence posts and you'd have to fix it. Possibly also round up any escaped sheep)
You're just salty because you've realised you're expendable. Don't feel bad, I am too. But in reality for a community to survive, they really only need food and rudimentary medical services.
