"if midwives are supposed to "protect natural birht" against their patients' wishes"
It's not their decision as to whether the mother has a c/s, an instrumental birth or an induction, so that's out of their hands anyway.
And tbh, I've yet to meet anyone who actually wants an instrumental birth or an emergency c/s if they could get their baby out safely without it.
"she definitely isn't there to fulfill your idea about what her birth should be like"
It's not the midwife's idea of what birth should be like. It's how the body works, if it's working normally. She's there supposedly to optimise the normal physiology of birth.
That said, if a mother requests an epidural then the buck stops with her. It's not for the midwife to make the decision for her.
Re: tokophobia, I'd suggest that even the most ardent and naive student midwife acknowledges the existence of tokophobia and birth trauma, and I see nothing in their comments to suggest they don't sympathise with women who have mental health needs connected with giving birth.
