2scents, you seem to consider an advantage for the community to get natural immunity quickly. If you mean that almost anyone gets sick, then it means that everyone at risk got sick and possibly died. I don’t think you mean that. I see two ways to get advantage of natural immunity:
1) expose young mobile population to virus. they are responsible for propagation, and thus protect elderly as yungeles will not be infecting them. Interesting idea, but it requires some discipline during that early stage – youngsters get sick but do not communicate with elders. Might have worked with those elders who isolated, like it seem R’ Edelstein @ Ponevezh did. Still, a lot of propagation goes through middle age working age population and exposing them all might mean a lot of death. Maybe this could have worked early on – ship all younsters – or all elderly – to a different location (Catskills, Florida) for a month, let youngsters get sick, and bring everyone back.
2) get early virus to avoid later deadlier variant. So far, it seems that “popular” strains alpha, delta are more contagious rather than more deadly.
