And the tribe can decide if abortions are to its benefit and what medical procedures doctors are allowed to perform.
And women can decide to not get pregnant. And that's what they decided to do in Poland.
How would Poland benefit from more abortions?
Pawian already partly answered that question.
Because of the present law and resulting doctor's fear of repercussions for saving women's lives at hospitals by performing an abortion women are afraid to get pregnant.
If the law changes, women will be less afraid to get pregnant and that will mean more kids - that's your pragmatic benefit from "more abortions".
A woman can simply deliver and just walk away.
What a bullsh1t. The societal pressure is on the mother to take care of the child, so she very rarely can just "walk away". And it's not like someone puts a gun to a guy's head and tells him to impregnate a woman lol You need two to tango.
Actually, delivering a baby is good for the woman's health.
Sometimes it is, sometimes it isn't. You can get thyroid problems, diabetes, autoimmune diseases, hemorrhoids, postpartum psychosis, liver problems, etc. due to pregnancy. I'm not even talking about changes to your body. When my mother was pregnant with me she started losing her teeth, btw.
