Whilst I really sympathise with you and believe that maternity care needs huge improvements, I don't think anyone should choose to get pregnant if they are so against medical care.
Regardless of how bad an experience someone had in hospital, not accessing life saving treatment, should you need it, is selfish. Parents don't have the luxury of being that careless with their own health.
Home births, with transfer to hospital if needed, are an option for women who believe birth will be easier and less stressful at home.
