Sure, I would. But I insist that it be real viability, not theoretical viability. In other words if the woman could actually go to a hospital and have the fetus removed, just because she asks for it to be removed, fine. I know that there are many cases where premature infants born survive, but there are also many cases where despite our technology, and heroic efforts on by qualified medical experts, infants born prematurely do not survive. Right now there is no hospital in the world that would induce labour or perform a C-section anymore than 2 or three days before the due date. So in real practical terms the fetus is not viable before that point (it cannot exist as an individual)
But back to the idea of your manufacture humans (glad you got my reference). I would say there would be a similar point. At some point this manufactured fetus would be able to survive on its own without the life support equipment of the manufacturer. At that point, it is an individual. Before that point, the person responsible for manufacturing this person could decide to abort the process.
