I actually really appreciate that you are thinking so deeply about this bumpity, and I'm glad of the challenge to my thoughts.
Here is where I land on the FGM example you raise.
There is a patient, and a doctor who is duty bound to act in her best interests, and to do her no harm. There are two parties involved.
Who is the patient? The woman.
If she were to harm herself with FGM, would I criminalise her? No. She has autonomy over her own body. She should have.
If a doctor however acts upon her body to do her harm - he or she should be criminalised. This is harming another person, breaking the Hippocratic Oath, and breaking the law. A woman cannot give consent for a doctor to harm her, just as she cannot consent to be murdered, because no murderer can claim or use that 'consent'.
I feel the same way about prostitution, and the sale of organs. A woman might wish to consent to having sex with a stranger, and she is free too, her bodily autonomy is sacrosanct.
But the man cannot purchase her consent, as HE in doing so commits a crime. Purchasing access to a woman's body renders consent void - if it is bought then it is coerced, and it is not consent.
In both scenarios the woman's bodily autonomy is not affected. It is the other party that commits the crime by purchasing or harming another human.
In the abortion scenario the procedure itself is the choice of the woman, and is in the best interests of health of the woman. The doctor can facilitate this procedure knowing it is her wish and will be significantly less harmful or risky than full term pregnancy and birth, and certainly than self inflicted abortion.
This proposed law would potentially criminalise a doctor and her patient for the open exchange of factual medical information about the pregnancy, and it would legally compel a woman to proceed with a pregnancy against her wishes and at risk of the detriment of her health.
It places her value to society in producing female babies above her bodily autonomy. It's forced birth.
