I have read arguments that unsanitary masks, for example, resuing masks without cleaning them properly (which I have been told is at +90 degees Celsius) is not a healthy practice. But to make a policy, one has to measure the risks from not wearing masks (eventual Covid infection) vs risks of wearing masks (bacterial infection). At the time of peak infection rates, it was sensible that the former risk was higher hence the policy for mandatory masks was necessary. But during current low infection rate period, policy might need to be reformed after calculating the two risks again. Hence the dissatisfactory mood of the public "For how long will this go on?" Of course then there are non-physical risks like social perception, social relationships, discomfort and so on and so forth which are more difficult to quantify.
