Some people would rather give themselves to the devil (whether you believe the devil literal or figurative) than refrain and take a wiser approach to life, just to prove to themselves that they are free. They've only traded one supposed slavery for another one that is all too genuine.
To insist a government pay for your controversial choice is to egg on social attitudes that, one day or another, will start to insist that you take this choice when it's convenient for society. It won't be to keep YOU from being "punished with a baby." It will be to keep the earth, or society, or your country, or whatever, from being "punished with your baby."
