Ideally that would be the case, however as I'm sure you're aware, laws are introduced under the guise of religion for example making homosexuality a criminal offence, outlawing abortion and contraception.
On top of the law, there is community and familial pressure to conform to religious doctrine. Patriarchy and misogyny is ingrained in society and religion can act as a stick to enforce it.
Without legal abortion, women and girls are forced to seek backstreet abortions. In the case of child pregnancy, it can be dangerous for a girl to carry to full term. In the case of rape, women and girls are forced to have children they didn't consent to conceive. Without abortion women are forced to give birth to babies that cannot survive or have complex disabilities they may not be equipped to deal with.
In the case of women who cannot use contraception, where it's either unavailable or outlawed by religion, they are forced to have children they cannot afford which drives them further into poverty. Unable to use condoms, women cannot prevent STDs and HIV.
It's all very well proclaiming from a privileged position in a developed country, that everyone is entitled to choose or deal privately with the consequences. That's not realistic for millions of people who live under the yoke of religion.
American women and girls in states that have banned abortion, have no autonomy over their bodies. My aunt lived in a country where contraception and abortion were banned and had 19 children.
Some people live in a dreamworld.
