Ad 2. No, you omitted mother-child bonding during pregnancy, because it gives the mother an advantage. Also, breast-feeding is how nature intends it, milk formula (invented relatively recently) is a crutch. So it does give women an advantage over men. As for midwives - they are women, not men. Following your reasoning, we could say "there is nothing that necessitates sex between a man and a woman" - because we have in-vitro conception?
