We aren't banning cars because we understand the cause of automobile fatalities. There are well defined laws and regulations implemented to curtail those fatalities. But people still choose to drive irrationally, they choose to disobey those regulations, violate the speed limits, so on and so forth putting their and other's lives in danger. Going by this analogy, implementing mandatory masks is one such regulation to prevent covid infections and deaths as is implementing traffic rules to prevent automobile fatalities. Since we have not had enough time to deeply understand the spread of this virus and its affect on all of us (unlike automobile fatalities), the state has no choice but to follow the safest policy that seems to work. But, of course, you are right to question whether this policy is the best we can do or not which remains to be seen as we witness the coming months.
