Because not everybody is able to afford the $30,000 hospital bill +
Also those hospitals you so admire sometimes literally kidnap the babies to do things to them against the parents wishes.
A lot of folks these days skip hospitals all together and go to a specialized birthing center where they are treated right and the parents are in charge and none of this doctors with a god complex and men with guns to back them up B.S.
Your statement of it being negligence is just pure ignorance and wrong (I'll stop there so as not to get worse).
Most humans in the world are born outside of hospital and most are just fine.
In my family, recent childbirths ranged everywhere from in a back room of the house with a midwife to a government clinic with a couple nurses, to hospitals, to clinics in Africa.
I'd avoid a hospital for childbirths unless it was high risk. A birthing center or midwife is usually just fine when you are close to a major hospital for any complications.
……… but as a nurse with over 35 years experience …… lariat is correct ……… I have been in situations where the family should have been in the waiting room the whole time, because their panicked a$$ made the situation worse when $hit started to go bad for momma and baby. I have been blessed enough that the outcomes were ultimately always good 
…… but 90% of the time it was the mother Of the mom whose mouth/attitude the made the situation even more dangerous 
……… I will never work OB/GYN again
