"Policy makers", aka the government, should be weighing actions depending on their outcomes as projected by expert consensus. That weighing should be to optimize according to a pre-defined value system, which of course is a matter of political deliberation.

To prefer personal interests (like not to have to wear a mask) over common interests (to protect against pandemic effects) incurs the negative consequences irrespective of whether one pretends to know better than the experts.

To let others play dumb and act against society is to be dumb yourself.
