It makes interesting coffee shop talk for professors and grad students with little else to do, but from a libertarian perspective, I think we should actually be less worried than before. In recent history, it's States that have inflicted the greatest toll on human civilization, not murderous, roaming gangs. And how can a roaming gang achieve that level of death and destruction without legitimately extracting resources at gunpoint from a defined territory?
But, don't misunderstand: the theory of deterrence in general is disgusting, immoral and perverse. It's just that plenty of intellectuals, politicains and public figures support the theory as a guide for interstate relations, why abandon it now in the face of The Virus? Surely thousands of innocent Muslims should pay the price for the actions of a criminal gang, right?
It's tragic that proponents of such a theory, which amounts to advocating mass murder, are allowed to operate freely in the public sphere with our tacit respect and without ridicule.
