If we want to be technical you can make the argument with that logic that anytime a woman has a period is a potential for life/a great individual that is wasted and we are possibly throwing away a great person. So obviously the only moral thing to do is to make women always pregnant. :P

Obviously there is a continuum. We have something clearly human, a newborn baby, and something clearly not, a gamete. The discussion now lies on where the line is drawn.
