On the last point: 1) The vaccine isn't perfect, and herd immunity nonlinearly reduces the risk of everyone including the vaccinated from getting it. 2) Unvaccinated people, who make up the vast majority of the cases, create an environment for the virus to evolve within, possibly mutating into a form that is more dangerous to everyone, including the vaccinated |

I would argue that the data now shows that herd immunity is not achievable with any vaccination rate. The vaccines just don't work that way, breakthrough infections are rampant.

This is speculative. Vaccination-induced immunity is clearly not perfect, at the same it puts selection pressure on the virus. Natural immunity, going by reinfection rates, appears to be much stronger. I would speculate that in a population where 70% are vaccinated, where the amount of infections among the vaccinated is roughly the same, the virus is much more likely to mutate in the vaccinated individuals.
