And superficially - especially looked at from our current generation's time - that seems to be a pretty reasonable argument.
There's just one big glaring hole in that argument: prior to modern medical interventions, giving bilth was the single most likely thing to kill a woman of child bearing age. In the 1850s, those with no access to even the rudimentary level of medical care (i.e. slaves) had a 20% chance of neonatal mortality.
In other words, the "natural" process of birth killed 1 out of 5 humans who attempted it.
"In the 1850s, the infant mortality rate in the United States was estimated at ... 340.0 per 1,000 for African Americans"
In addition, another 1.5% of mothers die from the process with no medical intervention.
"Bearing a child is still one of the most dangerous things a woman can do. It’s the sixth most common cause of death among women age 20 to 34 in the United States.""In the United States today, about 15 women die in pregnancy or childbirth per 100,000 live births. That’s way too many, but a century ago it was more than 600 women per 100,000 births. In the 1600s and 1700s, the death rate was twice that: By some estimates, between 1 and 1.5 percent of women giving birth died."

That makes it a medical emergency.
