Good point. And yes, conception is necessary, but surely not taking part in the act of conception, sex, destroys even more haploid probabilities than not doing so, thus stopping even more "inevitable development of mature humans".

>when a woman is impregnated the child is inevitable unless something goes wrong, you must act to stop an inevitability.
No human act is required to stop the "inevitability". Natural miscarriage happens all the time. By some accounts, miscarriage is a more common phenomenon than man-made abortions. But I wouldn't know if that's true, nor does it matter for my argument. Any amount of natural occurring miscarriage denies the "inevitability" of pregnancy resulting in a mature human being (without the human act of abortion of course).
