All your arguments seem to be variations of the "Violinist's Argument" - here is a synopsis of the Violinist's argument:
This argument is along the same line as someone comparing the fetus to an armed intruder in your house.
All of these arguments at least acknowledge that the fetus is a person. But they still all fail.
The first false premise is that we must see the baby in the womb as a trespasser or a parasite and turn the mother-child union into a predator-host relationship. This is clearly unbiblical and thus all your analogies fail immediately.
Second, in the violinist illustration, the woman might be justified withholding life-giving treatment from the musician under these circumstances. Abortion, though, is not merely withholding treatment. It is actively taking another human being's life through poisoning or dismemberment. A more accurate parallel with abortion would be to crush the violinist or cut him into pieces before unplugging him.
Third, the violinist analogy suggests that a mother has no more responsibility for the welfare of her child than she has to a total stranger. The "Self-defense" argument view is even worse. She argues the child is not merely a stranger, but a violent assailant the mother needs to ward off in self-defense.
This error becomes immediately evident if we amend Thompson's illustration. What if the mother woke up from an accident to find herself surgically connected
to her own child? What kind of mother would willingly cut the life-support system to her two-year-old in a situation like that? And what would we think of her if she did?
Blood relationships are never based on choice, yet they entail moral obligations, nonetheless.
