I see plenty of countries out there where masks are NOT universal.
Watching Australian Rules Football with light, socially distanced crowds. Nobody is wearing a mask.
Watching school kids returning to class in Denmark, no one is wearing a mask.
Where you see a lot of masks typically is in Asia where you always have. Probably due to air pollution as much as anything.
Australia harshly implemented the rules and that's why after 6 weeks, they loosened it up.
Ditto for Denmark
The key thing is killing off or reducing the transmission in 6 weeks of strict masks and social distancing -- then you can open your economy up as in Denmark and Australia.
