As a counterpoint, in Spain where I live, mask wearing in public is very high (Statista says 95% always wear a mask) and we still have a lot of lockdown measures, as infection numbers are still fairly high. You could argue that we have lockdown in spite of high mask use, due to cultural habits/private meetings/bad laws/low compliance of other measures, but it shows that high mask use alone isn't sufficient to avoid lockdown.
