Breeding ground for variants. Much more likely to happen in such a high infection population. Then they spread to the world.

  If the globe reached herd immunity as fast as possible then there wouldn't be enough time for any variant to become established. I'm not saying this would be a good idea, but Brazil is unlikely to be able to adequately vaccinate its population in the next year. This should be a consideration, as it was in March 2020 in several European countries before they adopted the chinese strategy.

    Reminder that herd immunity is a term only applicable to vaccines; what you mean is most of the population getting the disease and consequences. Please provide your estimate of how many deaths before "immunity" is reached.

That's obviously false, given that we are observing many meaningful variants without anything close to herd immunity. Each person infected is an additional chance of a variant with antigenic escape, let alone vaccine escape.
