"Government can be in many forms." not sure what you mean by this but okay, i hear your point. 

You can't have it both ways. You either have complete freedom, which includes autonomy, self sovereignty and self determination. Or you give these up, in any measure, to others - as a means of governance.

You give up your freedoms of self protection and get a number you can call instead. You pay taxes so that you can have public services available to you that you wouldn't have i.e. fire departments or parks or roads connecting your cities together. It's a give and take of 'freedoms' in a contract you make with the state. 

There's so many interesting case studies, from the current wars in Donbas and Palestine to the disasters in North Carolina and elsewhere. Even Bitcoin has a defining self-sovereignty factor to it, hell it's built INTO the original protocol itself.

At the end of the day, you need government to handle things so you can focus on other things.
