Lmao. The point is that there's always a chance you're going to trigger something. Wash your hands after you touch a dirty surface, not every time you touch anybody or every time you are in open air. Since most (reasonable) people don't wash their hands after every contact with anything ever there is always a chance you're moving pathogens. That is why lockdown and the masking didn't work. Not helped by N95s being pushed to the wayside by people saying only medical professionals should have them.
