We are thinking about masks wrong. You want every one else to wear a mask because they might have the virus, and if they do, the mask will stop droplets and aerosols from entering the air you breath and landing on surfaces that you may touch. And of course, you should wear a mask too -- to protect others. Had we all worn masks right when this started (simple cloth masks would do) this virus would not have spread so much and so easily.
