Viral pandemics do not respect your personal boundaries: your "right to be an idiot" over vaccination may not be intended to result in deaths, but that's what will happen if we indulge such beliefs until herd immunity is lost.

We need to draw a distinction between idiotic behavior with no externalities -- side-effects for others -- and idiotic behavior that can damage third parties. Upshot: there's no simple dichotomy between an open society and an authoritarian one.
