"The virus “rides” on expelled droplets of water. THOSE are big enough to be stopped by the mask"

This does work to an extent. for those breathing in bad air such as an airplane or elevator. The problem with it is Bernoulli effect creating atomized moisture. The person breathing out will create very fine water contaminated vapor which is far more dangerous to other people around them.

However, on March 15, 2021 the University of Colorado Boulder reported that a recent CU Boulder analysis of more than 72,000 test samples[https://www.medrxiv.org/content/medrxiv/early/2021/03/05/2021.03.01.21252250.full.pdf] collected from students and some faculty and staff on the CU Boulder campus between Aug. 17 and Nov. 25 revealed that it was a few “super carriers” with very high viral loads that were likely responsible for the bulk of COVID-19 transmissions, while about half of infected people were not contagious at all at the time of diagnosis. Among those tested (asymptomatic students in residence halls are required to test weekly), 2% of these people carried 90% of the COVID-19 virus. A related study[https://www.medrxiv.org/content/10.1101/2021.03.09.21253147v1] lended further credence to the idea that the amount of virus particles a person carries (viral load) is what drives contagion.[https://www.colorado.edu/today/2021/03/15/2-people-carry-90-covid-19-virus-and-roommates-are-safer-you-think]
