That's not troublesome at all because a "body in a stage of development that will become another person" isn't a person and therefore deserves no protections that supersede the rights of an actual person.
I imagine you also don't find it troublesome that people aren't forced into making organ donations when someone else's (another actual person's) life is on the line. If it was deemed that you were an ideal donor of a kidney for someone in need of a transplant do you think the government should be able to forcefully take one of your kidneys because someone else needed it to live? Maybe you do, at least that would mean you're consistent on bodily autonomy always being secondary to the lives of others (people or otherwise).
There is no arbitrary point at which "life begins" because reproductive cells are living human cells already. There's also plenty of precedent that places personhood at birth. So like I said, not troublesome at all until people start putting arbitrary (often purely faith-based) cutoffs on a biological process they they are completely ignorant about. Arbitrary cutoffs based on ignorance and faith shouldn't have any weight on medical decisions.
