I think the first part is correct. There is probably an optimal rate of c-section which is materially higher than "strictly necessary" and optimizes for mom+baby health. What I am concerned about is the scheduled c-sections. For most births, there is not really a medically credible way to determine in advance that vaginal birth will be dangerous (as a relevant corrolary, consider that there is no way to meaningfully determine the weight of a baby prior to birth).

C-sections are scheduled in advance (sometimes over a month in advance) because the American medical system has optimized for cost reduction (which includes extreme risk aversion) rather than patient outcomes.

Let's do it like with abortions- let people suffer, let's risk their health until it is clear they will die with intervention. Absolutely necessary is cruel standard.
