A society can have rules without having a ruling class. Think about rape. Rape is a bad thing, and virtually everybody can agree on that which makes it a rule. We don't need to give a group of people the right to coerce the entire country in order to stop rape, or any type of violence for that matter.

The whole idea of government for the last several thousand years has been to monopolize the use of force to the rulers. A system like this consolidates power to the top every single time, historically speaking, which is why virtually no gov has existed for more than several hundred years. Our "democracy" is only mob rule, whichever side wins gets to violently force the other side what to do. This isn't keeping us safe.
