Who are you, I or the State to say to woman; "You WILL carry your pregnancy to term whether you want to or not". Does the State OWN women?
That is why the US government did not decide that a fetus living inside its mother has zero rights over its living mother living inside the USofA. But all the US is saying is that if a woman chooses to kill the human life living inside of her, the Constitution does not give her that right. Also, a doctor who is licensed by each State does the actual killing of the fetus at its mother’s will and insurance pays$ but States have authority to pass laws governing if and when a doctor can kill a fetus(aka abortion) and insurance companies may not want to pay. That is how laws work.
Factor in that Uncle Sam can force your donkey into a battlefield which can end a person’s life, and that each individual State already has authority to abort any person living inside the State based on its Penal laws ( aka the death penalty).
