That's a rather strange position to hold. It brings in issues related to both the Prisoner's Dilemma and the Tragedy of the Commons. To whit, each individual reproductive group may desire more offspring, but each successively larger generation consumes more resources. Given a (for the foreseeable future) finite amount of resources, unrestricted population expansion is net harmful to society as a whole, even as large families may be beneficial (i.e. result in greater happiness) for individual groups. It's a coordination problem. Everyone wants to act in the way that maximizes their happiness/success/utility, but in doing so acts in a net-negative way. One of the premier purposes of government is to solve coordination problems. Why is it unethical for the government to solve this coordination problem? Or, more concretely, why does my right to have a dozen children trump my children's right to have sufficient resources left to them to live a happy life?
