“WITHOUT GOVERNMENT WE WOULD ALL BE KILLING AND EATING EACH OTHER!!!” But with governments too we are doing so, we are killing and eating each others, true and live examples are in Iraq,Syria,Kashmir(Indian occupied), Palestine, Afghanistan etc. what you cal the government please define it. And thanks to share very informative current affair post.
Government is a monopoly of force over a geographical region. You are a Government yourself as you own your body and the effects of your actions. We call this self-Government and all other forms of Governments are composed of this. State Government (federal, provincial, state, municiple, etc) is a bunch of individuals who claim to own all the people in their arbitrary area of control. Sadly, no two disagreeing governments can occupy the same space. It is the reason why you are never taught in school about your own self Government, because operating under your own natural moral code is against the rules of whatever dictator is in charge.
All of those places you listed have governments.
