The point is that monogamy is just one of a broad suite of strategies in play for various species that invest heavily in the rearing of juveniles.
Shinigami's original comments were specifically about the human species. Your points about insect reproductive strategies are not related to that. Furthermore, elephants are not polyandrous: they are polygynous.
Polyandry can work for species that can lay many eggs in a short period of time, and for species that do not invest in caring for their offspring. But, neither of these things is physiologically feasible for humans, so we're not likely to benefit evolutionarily from polyandry.
