My response to this would be dependent upon the current level of transmission in the region, which would inform whether or not such an intervention is worthwhile as a means to prevent loss of life. If new case rates are very low, the probability of asymptomatic transmission is very low, and universal mask wearing is probably not warranted. If new case rates are very high, the probability of asymptomatic transmission is correspondingly higher, and universal mask wearing is probably warranted. Another important input the the equation would be the % of the population with some level of prior immunity to disease. I'm not in favor or against any given intervention, I'm anti deadly infectious disease transmission.
