I don't think people should be entitled to the freedom of having children no matter what, since having children forces significant externalities on society, especially if there's an agreement that everyone should have a good standard of living (as implied by this article) or even just that there's a right to healthcare; and even without those, since the children may become criminals and harm others.
The root causes of poverty and violent crime are people who have children but are not able or willing to properly educate them and support them financially, so the simplest fix is to prevent that from happening (by forcing them to have an abortion).
That said, an alternate solution is for the state to step in if parents can't or unconditionally, although some sort of population control might be required anyway.
