I don't think it's weird to think about the type of birth you'll have as a child. I was ten when we did Sex education in year 6 and watched a video of a woman giving birth in a birth pool. I immediately said I want to give birth like that when I have a baby. Haven't ever actually had a water birth! Maybe I will this time? I'm a lot more open minded and go with the flow about this one, I think I've kind of had to be.
For me I would never judge anyone having a section even like you say "just cause" is a good enough reason, when I had an operation to repair my half severed finger a few years ago, they offered me the choice of general vs local anaesthetic. I initially thought I wanted local, but after speaking to the doctor about the risks and what would be involved with both I decided general sounded better for me, and it was.
The only thing I would worry about is that somebody choosing a c section might not be aware of the risks, but that's a conversation for anyone to have with their medical team, and there is a problem culturally as well where it's really hard to compare risk because we're not really taught to do it, but also because the information isn't particularly clear. So you get info about all these bad outcomes of c section but no separation between those done for medical reason vs those done electively, and even worse no separation between emergency and planned. So while there are risks of a section some of the stats are actually just outcomes of a high risk birth and not the section itself.
Likewise the risks of a vaginal birth are often given just taking into account births that end vaginally, which is silly! If I'm at high risk of an emergency c section then it makes sense to me to just start off with a planned one. This is never really mentioned in risk comparisons. Neither is the pain/experience of birth itself or the uncertainty. But you have to put everything on the table and let people pick up on what's important to them.
