A mask doesn't stop you from getting or transmitting Covid either. At best a mask is ~10% effective at stopping transmission and that's for N-95 and surgical masks. Those simply cloth things most people wear are much less effective (while the vaccines are ~90% effective).
Eventually, with most of the populations vaccinated, cases dropping, better treatments, and most importantly fatalities down sharply, people will learn to accept Covid as a part of life and death - much like we treat the flu today. When that happens, the Covid theater will largely disappear.
