Two problems with this.
First off, I'm not sure if you get the legal right to eject someone (who, again, is not there by their own fault, you know it was not by their fault, and it was probably you who brought them there, even if inadvertently) if doing so will cause them to die. Admittedly, laws may not be written with such a level of specificity because of the unlikelihood of such events happening (closest thing that is likely to happen is if someone who is unable to care for themselves gets evicted from their place of residence, though I would guess there are at least some kinds of laws to protect them in such a case). Which is another issue with your claim that people want special rights for fetuses, because if we had analogous situations where regular people were often ending up on other people's properties through no fault of their own, and probably through the fault of the property owner, and in which they would have to stay on the property for several months or die, then I expect we would see much greater specificity in laws that would prevent, or at least restrict, the property owner from simply throwing them out and causing them to die.
The second problem is that abortion isn't simply an ejection from your property. If abortions were cases of C-sections or forcing of labor, then you could have a point there. But abortions are far more commonly, as far as I understand it, done by killing the zygote/embryo/fetus, and then evicting it. So if we insist on this analogy, it would be a case where you kill someone and then throw them out after killing them.
