Is bearing a child really a right? The state does not know much about its own citizens other than date of birth and tax information so bringing unwanted children into the world is unfair to the child and the rest of society that must deal with all of the associated problems. Irresponsible parents or single mothers cannot guarantee the welfare or even the survival of their wanted children so why not prevent problems by passing a law allowing the state to licence and decide what type of people are allowed to have children according to certain criteria just like a driver's license? Those denied a license can always reapply at a later date once they've proved they are responsible enough. Right to privacy ends once the child leaves the womb since it is then a separate human and legal entity.
