Is it selfish to choose not to have kids?

No one owes the species the use of their body. That sentence should end the debate, but somehow it never does, so let me spell out what the alternative means. If declining to gestate, birth, and raise a human is selfish, then bodily autonomy is conditional on serving demographic targets, which is a short step from the state deciding who must reproduce. Every argument for the 'duty' to have children smuggles in the premise that women's bodies are public infrastructure. They're not. The right to decide what happens inside your own skin is the floor that everything else stands on. Remove it and what's left is a breeding program with good branding.
