Masks clearly have a measurable impact on mental health. Given what he know about aerosolization and cloth masks, masks are near useless in public spaces.
If we are talking about reducing the populations' micromorts[1] by reducing common freedom, then there are far better things to do. Enforcing helmets for drivers, breathalyzers ($70) as default in cars, banning right-turns on red are all significantly more effective at reducing total deaths than mask enforcement, with much lower costs to a civilization. Similarly, banning certain foods and mandating exercise would massively improve American health outcomes.
I find that 'masks for everyone and everything' have become more of a political rallying call driven by hysteria, than a principled outcome focused measure. It reeks of the same blind faith as those who shout 'trust science' while healthy discourse makes up a fundamental pillar of the process of science.
