I think current state of science is that good masks can both protects yourself and others to a varying degree and if used correctly. Of course I agree that we can't and shouldn't wear them all the time. "All freedom comes with risk", I like that sentence!

Personally, I wear a mask for example when I am sick and need to take public transport or have to wait at the doctor's. Especially in a waiting room, full of coughin people, it also makes sense to wear a mask for self protection. I don't want to go there with a hurting leg and come back with a nasty virus! 😷
