Because people have right to some choice in their care?
Right let's take another example
When I was younger I had some pretty bad skin issues
I was given some options for care ranging from antibiotics, topical something and roaccutane. The choice which one I wanted to try was mine and I made that choice guided by the dermatologist.
Another example
My mother had breast cancer. It was caught early so she was lucky in that she had some options in her care. They could remove the lump and some extra tissue and give radiation which would be an easier recovery bit require longer monitoring or they could do a slightly more aggressive approach (I forget the exact details as she didn't choose this). Guided by her care providers she made a choice for her own care.
Do you understand this? People have choices in their care.
Also as I've mentioned before homebirths can help free up capacity in the hospitals to help avoid situations like being turned away to another hospital an hour away or giving birth in triage.
To summarise choice guided by medical professionals is a good thing. Although you may just be one of those people that struggle to understand when other people feel differently to you.
