I'm gonna have my baby under my dresser and clean it with my tongue!!
sorry. i just got a really funny visual when someone said that. reminded me of my cat having her babies behind the chest of drawers in my bedroom.
I see the point you were making though, that we have instincts and that it is a natural process. I think women should have a choice as well but I think women should take the responsibility of being well informed. One way in which we differ from animals is that we walk upright and that has always posed a problem while giving birth. Our brains and therefore heads, are also larger than animals compared to our bodies, so that coupled with our narrower pelvis makes for a more difficult labour and birth. Some domesticated animals have help giving birth as well, like cows when they are calving. My sisters dog almost died having her puppies cuz one got stuck.
Anyway, it just goes to show there are no easy answers to these questions. I'm sure the women who make that decision put a lot of thought into it. I personally wouldn't do it, unless maybe it was my 10th kid or something.
