Where's your evidence that the virus is present in the air that people exhale?

  We know it’s a highly infectious respiratory disease with asymptomatic transmission, this isn’t rocket science.

    You've just destroyed your own argument. If you're wearing a mask to protect against droplets then maybe you'd get marginal benefits. But if your concern is virus carried in the water vapour that people exhale, then an N95 isn't nearly enough to protect you.

      Even if the mask is 10% effective that's still better than nothing.

        Not if it's causing people to decrease social distancing or to touch their face.
