For older children , any loving adult care is fine. But the original post was about the priority the mother has, indicating post-birth.

1. Let's replace "essential" with "optimal". The original point still stands.
2. You conveniently omitted the 9-month bonding time.
3. Formula is good enough, but breast milk is optimal. Never heard of midwives breastfeeding other women's babies in 21st century.
4. Researchers have long known that newborns recognize – and prefer – their mom's voice. http://www.babycenter.com/404_is-it-true-that-babies-can-rec...
2. Yes, I did. It didn't seem relevant to the point I was arguing, see #1.
3. For optimal, see 1, and for midwives—yes, and that's a societal trend rather than a biological fact.
4. True but still irrelevant, see #1.
I'm not arguing that biological mothers aren't generally inclined to want to spend more time with their children than their male partners, or that newly born infants aren't going to instinctively want to spend time with their mothers. It's just OP's original claim didn't logically follow from the evidence he presented—nothing about childbirth necessitates women having "the first choice to spend time with those children, and [...] bargaining power in relationships."
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?
