I get it, I'm just expressing my frustration with the one fatal flaw of secular libertarianism: economic growth benefits from demographic growth (or can suffer greatly from lack thereof) , and there doesn't seem to be a sufficient natural reward for having children. People will hire other people to protect them (i.e. handle guns), but not to have children who will be needed to fill the labor market when you retire. I believe this problem could fix itself with less government intervention in family and greater parents' rights, but that's a subject matter for another thread.
