It is higher risk though - it has to be. There is no way a midwife can have all the equipment that's available in a hospital. All the doctors I know are against home birth for safety reasons, and I really don't think it's part of some patriarchal conspiracy to control women.
Even if a woman is healthy you can't predict every problem - that's why there are emergency caesarians, because of complications that didn't become apparent until labour was established. I think basically with home births if you're fine you're fine, but if you're not you're a bit fucked. It takes a lot longer to rush you to hospital than it does to transfer you to another room in a hospital - you can't always guarantee there will be an ambulance available. It's more of a risk.
Most midwives are great, but they aren't doctors. They don't have the same level of medical expertise, although some seem to think they do and that is another risk - they delay transfer to hospital until it's too late, thinking they can deal with it but then finding out they can't.
I hate hospitals and would do anything to avoid them. But I would feel that I was risking my own and my baby's health by having it at home. No one ever tells you the home birth horror stories, but there are plenty.
Of course NICE support home births - it's cheaper. And because it's all about choice, if you or the baby dies they can't be sued because you chose it. It's a win-win situation [cynical]
