I agree with you on most except the last part, there will always be government of some kind mainly because people expect to have things done for them, education, health, security, transportation etc. since a long time ago just read about Saul in the bible, the other is this system is crumbling, that is practically the basis for Marx's ideas that the system was crumbling and would give way to a new system, that was about 150 years ago and it hasn't crumbled yet, in fact it's thriving look at the top, there are now more billionaires and multi millionaires per capita than at any other time in, as you rightly say, what we have been taught to be civilized history.
