This kind of thing is plausible to people because they have such little trust when the doctors tell them something is risky. And that's partly down to the medical community. The risks of scar rupture, for example, are often very over-blown, especially in the US, where almost anything seems to be reason for a c-section.
And of course c-sections have their own risks which are often minimized by doctors.Once people lose trust in the recommendations of doctors it's very difficult to have any good relation with them.
And frankly maternity care can be extremely coercive. With my third child the hospital wanted to me to have an IV in place the whole time as I'd been sectioned previously, I said I didn't want it, and signed a paper well ahead saying I understood the implications. Mainly I didn't want it because I knew it would tend to make me less mobile. Anyway, when I finally got there, well into labuor, the CoO said he didn't care, I would have one or he'd send me to the city an hour away in an ambulance. Trying to argue my position while in labour seemed hopeless, and I just told them to section me. (Which I regretted later but I was not thinking as clearly as I might have been. My poor husband wasn't sure what to do.) When I was in the waiting room a few weeks later to have my incision checked, every mother in the room had been sectioned!
