Nope. Not telling people what to do with their bodies. It's telling them what not to do with their bodies, viz no-one may use their body to aggress against another innocent human.
This imperative (ie legal order/instruction) axiomatically arises from the fundamental social and civilisational rule that the only legitimate use of force is in self-defence to repel the aggression of another, and then only against the aggressor.
Society establishes institutions such as government to give effect to this fundamental rule. That is why society (via its police and courts) will punish you if you use your body to intentionally assault or kill another, or take someone else's property without their permission. It's telling you what you may not do with your body.
The whole of society is vitally interested in protecting the life and property of each individual in that society. Without exception. Or should be.
In its legal institutions it does so primarily by prohibiting aggression.
Without this rule social living quickly breaks down and civilisation crumbles.
The prohibition is all-encompassing, includes all humans, and admits no exceptions -- It matters not whether the victim aggressed against is awake or sleeping, conscious or unconscious, old or young, dependent or independent, intelligent or stupid, large or small, black or white, citizen or alien, sick or healthy, handicapped or abled, willing or unwilling. Etc.
Babies in the womb are human babies. They are entitled to the same protections as any other human.
Yes, they might not legally be persons in the way the law uses that term for matters like inheritance, contract, liability, and so on. But they are emphatically human in every other respect. Like all other humans of whatever status or condition, they may not be intentionally or negligently killed.
Abortion is an horrific and unconscionable assault on a fellow human being.
Allowing it legally corrupts our legal system at its core because it makes an exception to the fundamental principle against aggression. Once society allows exceptions to the law against aggression, everything else is fair game. It's the line that cannot be crossed without bringing disaster on everyone.
Now we cannot completely abolish human iniquity. Murders, assaults, thefts and other aggressions will always be a sad reality. But under no circumstances can or should they become legally permissible.
