The way you define anarchy just establishes that it's nothing more than an chimera. There is has never been, not will there ever be, such a state as "an absence of rulers."
You also make a severe logical mistake by entailing that a sovereign can break rules. A sovereign cannot. This is law 101. The sovereign is itself not bound by laws.
If a sovereign can not break rules then one sovereign can not prosecute another sovereign for war crimes nor would there be wars between one sovereign and another sovereign in response to rules that one sovereign said the other sovereign broke
"In international relations theory, the concept of anarchy is the idea that the world lacks any supreme authority or sovereignty"
"International relations generally does not understand "anarchy" as signifying a world in chaos, disorder, or conflict; rather, it is possible for ordered relations between states to be maintained in an anarchic international system.[1]"
anarchy used to be considered the furthest right on the political spectrum but a bunch of faggots took it over and made it all leftist and gay. they did the same thing to libertarianism.
