Can I safely assume that this woman is the type that wouldn't likely get pregnant, if you catch my drift?
Otherwise, I don't particularly care whether birth takes place in a hospital or at home, provided that expert help and sanitation are taken into account. However, that's just absolutely insane. It's telling that not even ancient societies practiced "free birthing," and even they knew that was a dumb idea.

@Zwiebelkönigin 's point, it's for that reason why any philosophy that says nature is inherently good either has a rosy view of nature or thinks that the things that you mention are inherently good scares me.
There's a weird intersection between fundamentalist Christians and Neopagans when it comes to some of this "crunchy" stuff. Not to power level too much, but I've seen more of the former variety than the latter. Most Christian crunchy moms don't usually go as far as their neopagan counterparts, but they get dangerously close (e.g., vaccines). This sort of crunchy mentality seems very odd to me, given that nature is considered to be under the curse of sin: while there is order, it is a marred order. The weak get trampled. The mother dies or aborts its own fetus. If the father is till present, it will eat the young. In cases like black widow spiders, females will eat their mates, etc. One has to be very careful when defaulting to nature in arguing for the inherent "goodness" of something for the reasons you mention.
