The reason a lot of women want to avoid a hospital birth is because they are treated like shit by staff, and in many cases they strongly suspect or know that they recieved bad advise or management or that staff did not seek to manage their births appropriatly.
Just as an example: my firs birth was a section, after there was what appeared to be (or I was told) was an irregularity with the heartbeat. This was after I had been lying in bed, in one position, for hours.
The immediate recommendation of the GP on call was to give me a section. One older nurse wanted to get me up walking around a bit, which was poo pooed by the GP, and she did also try to see if I could start pushing as I was in fact a hair away from being fully dilated.
She was right of course, changing position should have been the very first thing done, and some walking and being upright. I was at the time too inexperienced and scared to really take in what was going on, but the young GP was just like an idiot mechanic following a set protocol without engaging her brain.
Women want births managed properly, hospitals in many cases want a cookie cutter protocol that does not mean staff has to stay with the mum and help her, and doesn't mean they will have mums doing things like walking the halls in labour, or taking up rooms for too long.
