Applying this article's standards: Seat belts don't work, because they don't prevent all fatalities. Don't use a safety rope while climbing, because your anchors can break and you can still fall. Safety glasses don't work, because foreign debris can still enter through the sides. Don't wear a life jacket, because you can still die in cold water. Don't get your teeth cleaned, because it doesn't prevent every instance of tooth decay. This is ridiculous. If wearing masks reduces transmission rates by 10%, it's still easily worth it. The cost of masks is tiny compared to the enormous costs of reduced economic activity (not to mention infection-related healthcare).
