Agree Bellebelle. Bottom line is, statistically home births are no riskier than hospital births. So actually, all the anecdotal stuff is really not relevant. For any home birth tragedies, there will be at least the corresponding amount of hospital tragedies.
I also think this point about women saying 'Thank God I was in hospital - it saved my baby's life' is interesting, because I bet it's actually incredibly rare that that is genuinely the case. (And as has been pointed out, where it is the case, the woman is likely to have been told she's high risk anyway!)
I think the natural tendency is probably that if you have a high tech hospital birth with interventions, you either go one of two ways: you convince yourself that you needed it, and therefore justify the choice you made to give birth in hospital. Or you subsequently feel unhappy and disempowered by the interventions. For the sake of your own emotional health, it's probably better to fall into the first camp - you only need to read some of the unhappy threads on MN from women who've had all sorts of unecessary interventions to see that it can cause a lot of long term unhappiness.
If I had given birth to my first baby in hospital, I am 100% certain that I would be one of those women saying 'Thank God I was in hospital, my baby could have died otherwise'. It was a very long, painful labour, she was a big baby, her heart rate was decelerating and the midwife in the unit had called in a doctor because she thought a forceps delivery would be necessary. But while the doctor scrubbed up ready for it, she talked me through the final pushes.
I can well imagine that in a hospital, I wouldn't have been allowed to labour so long, I'd have been pushed into the epidural route, which would probably have slowed things down even more, and no doubt ended with instrumental or even C section delivery. And then of course I would have believed that all this was inevitable!
