Anarchy. We still haven't figured out how to make something both an anarchy and raise the life expectancy above 15. Oh, and keep the anarchy going and prevent someone else form stepping in and imposing their disgusting order.
I'm fairly certain there's no way to prevent that. I eagerly await being proved wrong , though.
That works if you stick to the "Anarchy = every man for himself + chaos" theory.
Anarchist political theory is a whole different thing to that. Which make the individualistic chaos thing a straw man. It's clearly a straw man argument because it usually paints anarchism in a specific way, debunks the model they themselves created for the pure purposes of debunking, ignores any links etc which shows that the
very definition of anarchism in the political sense is completely different from the straw man they just tore down, and goes right back to the start. Circular logic.
First up, the idea that anarchism is opposed to "order". Not true. Anarchism is opposed to
the state as an institution. It's statists who hold that anyone opposed to the state are opposed to "order", in the exact same sense that anyone opposed to GW Bush was opposed to "freedom". There are broadly speaking a speactrum from anarcho-capitalists to anarcho-syndicalists (i know i'm missing out a lot of different ideologies but it's the main currents). Both of these currents propose some other "order". Neither of them proposed an every-man-for-himself individualism, which is something only held by a few fringe figures and teenage punks.
