i'm partial to /r/Anarchy101's reading list i think it's kind of funny how you say we'll eventually reach a post-scarcity society in which government is unnecessary and then immediately dismiss marxism, anarchism, and syndicalism which are pretty much the most complete bodies of theory on post-scarcity stateless societies. the idea that anarchist societies exist in a power vacuum is wrong. anarchists aren't simply trying to eliminate the state and property, they're trying to construct non-hierarchical social institutions that encourage cooperation, to eventually displace our current hierarchical social institutions that encourage domination. there's no power vacuum because the vacuum is filled with something else. furthermore, it's kind of a silly question in the first place, because the "failure" condition is actually where we are right now. when an argument against anarchism utilizes a state or other hierarchical system as a theoretical bogeyman, it's kind of fucked. any anarchist society will obviously have to overcome state aggression to even establish itself. by the time the society is operational and widespread, the question has become a moot point. AFAQ Section I.5.11: How will an anarchist society defend itself against the power hungry? AFAQ Section J.7.6: How could an anarchist revolution defend itself?if there's an absence of power, something will fill it
