> The ability to rely on another person's body to keep you alive is clearly a positive right if it exists

That is one way to frame it. Usually, though, abortion requires someone to actively kill the fetus.

And there is another problem with this argument. The sacrifice it takes for the woman to carry the baby for 9 months may not be the real reson people have abortions. Rather, I imagine, the real reason is that they don't want what happens AFTER the child is born.

Let's consider a similar argument: A ship crew on an oil tanker going from Saudi Arabia to Huston discovers an uninvited "passenger" hiding in the ship. A 5 year old girl, let's say. Do they have an obligation to feed this girl until they reach LA, or can they throw her overboard?

Now, from a purely postive rights argument, one could say they're not allowed to throw her overboard, but they also are not required to feed her. But we all know that's not going to happen.
