Ok, so, When people started to settle down from primitive nomadic life, then people started to live in groups or communities. Most of people will live like normal citizens and do the productive work. A few will do the protection work, from both external and internal enemies, and some will maintain the internal law and order. And people will pay them for their protection work, that's tax. That's all the countries and their governance systems today.

But today, that protection system has become monstrously big, bloated and dangerous, creating all kinds of problems everywhere in the world. The actual purpose the governance system is totally forgotten. It has to limited by limiting their budget.😀🎈☕👍.
