Unfortunately, life becomes more complex at every stage of the development of civilizations and the growth of government to deal with those complications is inevitable.
Do you seriously think you can run a city like NY or Chicago without government? I know Marx believed (or claimed to believe) that government would wither away after the Revolution and the dictatorship of the proletariat but that does not happen experience shows us.
No one except you said NO government. What is the role, how big shoul dit be and how much it should cost.
