Very good article, as usual! On the other hand, there is an argument that I very seldom see anywhere. Irrespective of the mechanistic theories or evidence, that fact is that the vast majority of people (with no symptoms of disease) in a community are not infectious. They are not shedding any virus. So, irrespective of whether masks can stop a virus or not, it makes no sense to have everyone in a community wearing masks. We have no reason to think that everyone around us is capable of giving us an infection just by passing nearby. People have been convinced of believing the absurd.
