Dave, I would respond to your post, if I knew WTF you're talking about.<quoted text>
Challenge it on the grounds of interstate commerce or the common good.
The government has a right to limit activities that can be harmful to the maintenance of the nation or public good by improper use of resources. Personal decisions of whether to continue the process of creating a resource the nation needs to stay a viable entity providing for the good of all can lead to the supply of such resource being reduced or even eliminated. People are the prime resource for humankind. They can't live without them.
The act of creating was initiated voluntarily in most cases. Such usually then draws upon public resources in some fashion, such as pre-natal care, which I believe is a given under Obamacare. I believe termination is also included, as is prevention. Prevention allows for personal choice before drawing upon public resources.
The child is needed for future taxes and support of the whole. Society has an investment in its production that trumps the ill conceived actions of the individual that initiated the process.
It isn't a matter of personal liberty, it is a matter of survival of the species.
There is probably a considerable body of law already in practice that has supported similar legislation, and even in advancement of your social agendas.
