At some points, I wonder how the world would be without a governance, I don't care to know about histories of how politics and government has been in existence before these days.
My interest is ... Could we (humans) had lived a peaceful soul here on earth without a governing body and no laws?
No I don't think it's not possible to human lives life peacefully on this earth with out no government or no laws. If there is no government or ruler to control a population then the people will take the law into their own hands which will result in one group killing another group or one person killing another person freely. I think if this happens, the world will be more chaotic. Moreover, in the current situation in which the world has come, it is impossible to think about the future without the government.
I think Op needs to read about Thomos Hobbes works about the State of Nature how life was solitary, brutish, and short as a result of lawlessness of the then society before the emergence of states serving as the sovereign for the protection of human lives and property.
With how I have seen life become in this present day despite a government in place with all legitimacy of coercion against all acts of lawlessness yet society is still proven to be dangerous then how much more when a State cease to exist. I don't wanna imagine living in such society now.
