We are likely both wrong in some way, what a novel concept! ;) Having parts of the spike protein targeted helps with existing variants, but not with new variants that might escape those markers. Delta is weakening the effects of vaccines already. Sure, booster shots might include new markers, but it's still a narrow moving target. However, natural infection will provide broader immune response and antibodies. So if one could be sure to remain in good health, infection is much less terrible after two vaccine shots. That might provide additional protection that vaccines may not. It's more random though, but researchers are not foreign to the idea. Nobody is able to predict future outcomes of it, but at some point society will need to accept widely spread of infections and deal with those outcomes. Hopefully, vaccine shots is enough to deal with the initial shock so the body can do the rest. It's not just about avoiding killing old people, but also avoiding degrading public health too much.
