That is precisely what legislators did when they voted for both the Abortion Law Reform bill (passed in both houses of the Victorian Parliament, only amendments may be possible) and the Assisted Reproduction Treatment bill (passed the lower house). These are votes to repeat the mistakes in other countries. A generation stolen from the womb, or a generation undergoing social experiment.
Update: Here's an argument for the social experiment of redefining parenthood and raising children with any number of parents. Good luck finding data to support that. Oh, that doesn't really matter, does it? That explains why they didn't bother with data.
