Ok, seriously, what should be the approach on a societal level? The whole point of masks and isolation was to prevent spreading not in general for the sake of preventing it, but as a way to "flatten the curve" as a way to make people get vaccinated hopefully before catching it for the first time, and to prevent the overload and collapse of the sanitary system.

I'm asking from ignorance because I'm not an epidemiologist, whether it makes sense for individuals to wear masks to slow the spread during normal periods of healthcare not collapsing, and in a scenario where already the overwhelming majority of the population has been exposed to the virus and to vaccines; or whether it's best to let people get immunity through normal exposure to the virus as we've been doing with basically every other seasonal virus in existence (with vaccinations available for at-risk individuals)
