I don't understand. Human beings are capable of performing many tasks without the state. Including building roads and infrastructure. The government is just an entity made up of people. This idea that because the government does something now, it can't possibly be done any other way shows a limited line of thinking. People historically used this argument to justify many other forms of coercion once considered acceptable. It doesn't make sense then, and it doesn't make sense now.

The humans that comprise the current US government had no part in any of those things.

Nations are a way of making people proud of things that they did not do, and making people hate other people that they have never met.

Are you really denying that you're relying on the courts and police to – for example – protect your property?

Yes I am. Police/Courts works because people are non-aggressive. And when you do get in trouble, Police/Courts should be last in your list of things that will help.

Have you lived in an area with high rates of theft before? I have (parts of New Zealand) and IME the police really don't care.

I 100% do not rely on police or courts to protect my property - because they don't.
