Certainly, but even you might admit that, since masks inhibit droplets, and since there are viral particles in droplets, there is a decrease in viral dissemination with masks.
Not a significant decrease if people are in the same area for more than a minute, if they don't have a fitted N95 mask without a vent hole, and not if they don't change out their mask with a new one fairly frequently.
It's a security blanket at worst. At best it might help a little. Whatever floats yer boat, though. If anyone wants to go, they'll probably have to wear one.
