proof you don't really need a government or state in order to have rules and order. this seems like a win for anarchism and a point against statism.
It’s proof of the opposite of your conjecture.
Anarchy always rapidly evolves in to government.
Whoever, or whichever group, performs the making, administering, and enforcement of rules, is the government.
but regardless, if you want to call the state in anarchism where people collectively form together to create rules and order "government", be my guest
