I am, I must confess, getting a bit irritated with my resident troll for claiming that an AnCap society would be defenceless against predatory criminals.
The first thing that I'd like to point out is that an AnCap society would inevitably a better armed society and states in the US that allow "carry" have lower rates of violent crime than states that do not. Although the murder rate is high in the US overall, it's high because "non-carry" states have very high rates.
So, individuals would be much better equipped to defend themselves against criminals than they are now.
The second thing that I'd like to point out is Kinbingo's own admission that AnCap advocates often create structures very much like what the state offers for our protection, only privatised. So they'd be cheaper and more responsive.
In what way does this leave an AnCap society defenceless?
Look around you, Kingbingo. Look around you.
