Reality is there are rarely to the death true libertarians or authoritarians, only those who lacked the opportunity in the monument to change their positions when significant threats or opportunities are presented. The optimal degree of control in a system is based on context, both for the individual and the system itself. To think otherwise is just illogical and discards the complexity of the world for a theoretical utopia.
Anyone that believes to the death libertarian bros exist doesn’t understand the people they’re referring to — which to me is a larger issue than people behaving rationally.
