basically I agree with what you wrote except for that line.

Efficiency has nothing to do with founding gov'ts.  Gov'ts are the least efficient allocators of resources known to man.

Many/most gov'ts were founded by gangs of thieves who conquered and subjected others in order to exploit them.  Some/few were founded by people to protect the people from gov'ts of the first order, but none remain of that persuasion to my knowledge.  Some have tried to dress themselves as if the people/society were a priority, but the laws, constitutions, and actions when observed in action do not support that stance.
