I think this is one of the situations where there is no scientific study to be able to make an informed decision.
The CDC has said over and over that asymptomatic individuals can still pass the virus and that it's mostly transferred via respiratory droplets. The mask would at least reduce transmissions.

I understand people might be taking away masks from trained professionals but if everyone wore even basic masks it would stop droplets on the spreader and spreadee side of things and keep people from touching their mouth and nose. Some type of glasses would be a plus too.
That's different from the lie which is being given to the population: that they don't help.
Frequent hand washing and sterilization makes more sense to me. The cough droplets are on surfaces we touch. You aren't going to inhale them.

Most people will not intuitively remove gloves in a hygienic manner. While this can be solved with education, the gloves without the education is false protection.
