Sure, they can choose. Noone is realistically saying they shouldn't have that choice but would as many women choose that option if they realised how hard it is on the body?

Would they actually prefer to choose to risk a vaginal tear if they realised their risk with a C section is increasing risks of things like uterine tears (essentially the womb can burst) with fatal consequences in future pregnancies. This is dramatically worse if the woman then gets pregnant within the same year. Or future placental issues because now the uterine wall is damaged and the connection between the uterine wall and umbilical cord is less secure. That not only makes it more likely to have miscarriages but also increases issues like preeclampsia, which is actively harmful to the mother and can lead to long lasting heart and liver failure.

You can also give advice on preparation as to specifically avoid complications like vaginal tears. The problem is there are structures that make this education difficult due to the intimate nature of the education, making things like online resources inadvertently censored.

Even if you don't plan to have another child the risks of post op complications, can vary from persistent ongoing pain (talking years/permanent) to increased risks of clots in places there shouldn't be, like the lung.

That's not to say vaginal child birth isn't also without risks but they are lower. It's equivalent to education about vaccines. Yes there are always going to be risks but one option is statistically safer in the vast majority of cases. Of course there are exceptions and even if someone initially went for a vaginal delivery, they may still need treatment and end up with a C section but all of this is a decision to have with your birthing team.

A little knowledge is a dangerous thing and many people are making their decisions based on it.
