The relative freedom of various societies is hardly a useful topic in these discussions anyway, since nobody can pin down what freedom is. Is a society without laws 'freer' than one with laws? Superficially, maybe (that seems to be the level at which 'freedom' has been considered so far), but given freedom to act many people will freely take away the freedoms of others, whether through some antisocial action or neglect, or just by killing them. If we ban antisocial behaviors, restricting freedom, but thereby render people free from the negative consequences of those actions, have we actually expanded freedoms? How do we weigh negative freedoms versus positive freedoms? How do we weigh the distribution of freedom within a culture - is it more important for fewer people to have more freedom (as in capitalism, where it's possible to accumulate enormous capital, but probable that you won't and that your range of action will be comparatively restricted), or for everyone to have a little freedom (as in some notional leveler state, where everybody is guaranteed social services, but no one can accumulate the capital to undertake large projects)?
Is a truly anarchic society, where your risk of death by violence or misadventure is high and the infrastructure is basically nonexistent, free - given that only a narrow spectrum of actions permit your survival, and few actions at all permit you to exist in anything but a subsistence mode?
