Every argument for abortion in the womb can equally justify killing a baby five minutes after birth — the baby is just as dependent, just as unaware, just as small. The moral distinction collapses.

Infants aren't self-aware, people in comas aren't self-aware, but you can't kill them. A newborn is just as dependent on the mother as a fetus. If dependency, size, awareness, or location determine value, the logic permits infanticide. The moral framework breaks down.
