Again, it's a chicken and egg thing. I think you don't sustain a free society(nation?) unless the members of that society are committed to preserving the values/morals that created it.
What you need is a nucleus of individuals around which such a society and culture can grow and which cannot be easily disrupted. Historically, the state always acts to disrupt this /1
I see a lot of ancaps using "the state" as an ill-defined slur, much like you'll get a Marxist screaming about "capitalists" but then it always ends up being the same gangster assholes
The state is pretty well defined, no? OTOH, socialists always cherry pick what they mean by "capitalist" which always means some billionaire govt. crony, not a wealthy dentist, etc.
