I'm not even beginning to see your side of the argument here, and it's really not helping me understand you.
Fundamentally, moral systems deal in the interactions of conscious beings. Folks in this thread have been using "human" to refer to those beings; for clarity, I'm going to use "person" instead.
Modern culture's still working on how we treat non-human life that still possesses a more limited form of awareness, emotion, cognition. The traditional model is absolute non-personhood. Modern radicals occasionally suggest absolute personhood, but that position is untenable (see below). The idea that, in addition to the personhood of real, living beings, there are
degrees of personhood (and therefore, yes, of moral importance) that apply to other life, is slowly taking shape. (There's a kind of elephant-in-the-room tangent here that I'll address later.)
You can't completely change how a person acts just by creating a handful of new moral ideals. A large part of any moral philosophy that has practical value is really a set of rationalizations -- we're formalizing our emotional thinking. This has value because we can then take the formalizations and apply them to situations that are too complicated or too alien for our instinctual, emotional, subconscious reactions.
I threw in those last two paragraphs because, simply put, all life can't be equally magically sacred. We kill stuff all the time. It's just how we work as biological beings. Even if you think that's universally bad, you have to actually recognize moral
degrees there; otherwise you're paralyzed by a value system that values all actions the same.

If it is going to become a human if we do not interfere, then at what point does it get human rights? When it is outside of the mother's body? Is that what you are saying here?
Morally speaking, it acquires personhood gradually. There shouldn't be an arbitrary line. Not fertilization, not implantation, not second trimester, not birth. Because of how humans develop, killing a third-trimester fetus means more than killing a two-week-old embryo.
To work this into a modern legal system, you have to distill the fuzzy moral spectrum into specifically-delimited legal categories. Legal systems don't have to match moral systems perfectly; I think effective ones shouldn't -- they should allow some flexibility for people to act within the parameters of their individual moral ideals, as long as those moral ideals are at least someone in tune with those of the
society as a whole.
So, here's some arbitrary categories just for the sake of example...
Given that a first-trimester child is definitively less conscious than the pig I had for dinner today, I see no reason for a woman to be legally prohibited from killing it for pure family-planning reasons (what some people in this thread are calling "willy-nilly" or "escaping the consequences").
Given that a second-trimester child is, at most, not much more conscious than that pig, I think killing it is a bigger deal than killing the example first-trimester child, but I think there's no question it should be legally permissible. And my lifetime of pig-eating is quickly adding up to more of a moral transgression than a one-time abortion.
Given that a third-trimester child is getting much closer to a full-on infant, I think killing it is a big deal morally. Legally, though? In theory, it could go either way and I wouldn't complain: this is a fuzzy edge, so I don't think where we draw the necessarily-kinda-arbitrary line really matters as long as it's vaguely within the right spot.
In practice, I'm in favor of laws that permit late-term abortions for non-critical reasons because I think that the threat of people using those laws against women who
need a late-term abortion is far greater than the threat of people getting unnecessary late-term abortions -- women who get abortions for family-planning reasons rather than out of medical necessity aren't going to spend months carrying the child beforehand.
This idea of interference is irrelevant. We "interfered" to make the zygote in the first place. We don't owe that one imaginary person anything. We can take its probable future into account, but, when we kill it, we're killing the thing it is now, not the thing it might become later.

Also, are you saying that if something cannot perceive and interact with it's environment, we should be able to kill it? There are humans with disabilities that cannot do this, should we just knock them off, too?
These concerns come up a lot in the philosophy of artificial intelligence. Albert Einstein's mind magicked into a rock isn't an intelligent entity.
In a practical sense, any person that meets your criteria absolutely is braindead anyway. It's irrelevant. We keep coma patients alive because their condition might reverse itself; for people we know to be actually braindead, the so-called "right to life" issue is really a matter of social ritual rather than actual moral significance -- it's just a slightly more visceral version of the question "How should we dispose of our dead?"

I agree that it's right to life should not make an actual human suffer grievous harm, but if the human is not going to suffer grievous harm, then the fetus should be allowed to live. We have come up with this idea that abortion is a right, (as you put it, a body-right), and that this somehow supersedes the right to life, which is guaranteed in the US constitution, in any case.
My cat's more alive and cognizant than the vast majority of fetuses at the time of their abortion, and my cat has absolutely no legal rights.
The US Constitution deals with "we the people," not "we the potential-people". Its preamble stresses "justice", "the general welfare", and "liberty" as the essential concerns of America's highest laws. "Life, liberty, and the pursuit of happiness" is a phrase from the Declaration of Independence, which sets up some foundational ideals but isn't actually the document that established our government.

By the way, the fetus' brain begins its development, (as the brain is, really, developing all through life), a mere three weeks after conception. So is this the point where you would assign rights to the fetus?
That's the point I would start to assign serious moral weight to actions taken against the fetus. However, it takes much longer for it to develop, say, a brain with faculties similar to my cat's. And, as I said above, I eat things that used to have brains all the time. I don't think it's morally
good but I'm not freaking out about it, either.
