1) People that will get resistance via vaccines
2) People that will get resistance via infection
Some 30-40% of the US population decided on #2. Roughly 0.7% of them will die because of that decision, but this is exactly what they are asking for! If you are in cohort #1, you really don't have a lot to worry about from the virus. Why are you denying people the consequences of their decisions?
Yes, the medical system will be briefly overrun, and it would be a terrible time to need hospitalization. That's a good argument for getting it over as quickly as possible! The delta variant is estimated to have an R0 of 8-10. Let it rip and the surge will be over in weeks.
What about the children? Serious negative effects on kids seem to be extraordinarily rare. The kids will be fine.
I am only half joking here. "We live in a society" cuts both ways - we have to respect the general health of everyone, but we also have to respect the explicit wishes of a huge portion of the population - almost a third. The good news is that almost exclusively, they're going to be the ones dying. I can live with that.
