I've seen no evidence that masks give people a false sense of security. If anything, it seems to be the opposite. People report that when they wear masks, people move away from them, and employers have asked them not to wear them because they might make the customers feel unsafe. They're a giant reminder that things aren't normal and that we're in the middle of a massive pandemic. This is a good thing.

If mask use becomes mandatory, will there still be groups of people standing in the middle of supermarket shouting to each other? Sure, just like there are now. The difference is those people will at least have masks on.
