While I see where you’re coming from, the state does have practical, passive interest in procreation, mainly for purposes of military and taxes. If you have way too many old people and few young people, problems can arise. For instance, if a draft were instituted, you’d need to have a certain amount of people eligible to defend the country. It is a passive interest though. They cannot do things like China has done.

I agree and that’s the problem. That’s why the ‘state’ is now pushing gay marriage. It didn’t make sense before but now you have technology like in-vitro fertilization that allows gay people to procreate. This line of argument will inevitably lead to gay marriage and to polygamy, I hope you can see that.
