These are some great quotes.
Government is a necessary evil. The main reason it is necessary is to defend the population against sociopathic groups both internal and external...which are never going to go away. (My implicit assumption is that sociopathic individuals could be effectively dealt with by free individuals.)
Oddly enough, sociopaths have a value in society, as their emotional composition suits them for necessary violence. (Examples in the psychoanalytic literature include some military, law enforcement, CEOs, slaughterhouse employees and surgeons).
But given their existence (sometimes estimated around 5% of the population), a totally non-violent “Nation” will be very short-lived. It will be thoroughly victimized, its wealth and its women plundered by the first Hitler or mob boss to come along.
However, if sociopaths become organized
...However, if sociopaths become organized, they must be met by an organized opposition who can meet them with equal violence.
