People make the same argument for why women can’t chose what happens to their own bodies (eg rape victims opting for abortion). And some people make the same arguments against contraception too.

In all cases, yours and the above, I find the argument less than compelling because life isn’t something that exists prior to birth; you’re not denying a soul from physical form because you happen to farm fewer chickens.

Arguing that the absence of life is the same as death is really just a clever way of justifying selfish ideals.
