And then every single one of the resulting children shares a father? I don’t want a large quantity of children, I want high quality; limiting incestuous relationships via diverse mating pairs is the best overall course of action. Sure, re-population will go more slowly that way, but I’d rather have a slowly growing population that can take care of itself than a bunch of women launching babies non-stop from their gaping woman's genitalss and not having any idea what else to do.
