1) Wearing a mask while staying at a distance significantly decreases the risk of infecting someone else with the virus.
2) By that same twisted logic: No one should prevent me from pointing a gun at people because they are 100% capable of protecting themselves by wearing kevlar body armor and other shielding to stop the bullets.
Also, the highest rated filters N100/P100 are not 100% even when they are brand new and worn properly (assuming you can find one from a reliable source). And there is not enough supply for everyone.
Assume a population infection rate of 2% (actual rate, not positive test rate). That's like placing fifty .22 pistols on a table with one of them loaded. So you are saying it is okay to pick up one of the pistols at random and point it in random directions while pulling the trigger. Chances are it's not loaded. And if it is, chances are you won't hit anybody and if you do hit someone, there's a good chance that a .22 is not going to kill them. Therefore it's okay to pull that trigger, it okay to not wear a mask near other people. That's absurd.
Regarding amorality. It's not amoral to compel another person to abstain from negligent actions that have potentially lethal consequences.
