I can see some merit for wearing one as a reminder to maintain space and to prevent touching the nose and mouth directly.

Masks are not important if you are not sick - story has been pushed into media as the masks was short in production/supply and not to create more panic. Regular masks may not be as effective as N95 masks but still it will protect 80% of the virus(if they are flying with water droplets or small particles), which is still LOT compared to not wearing one.
Surgical mask = 80%
N95 mask or 3M 8812 = 96.6%
