Besides the moral problem, which is a big one, the problem would be how and who would set the standard, the rules...... because if somebody fucks it up (and it's easy to do since who knows what the future might bring) ..... it would be devastating. So basically. no, not a good idea.
You say "it would be devastating", but it's already devastating to watch drugged up whores you know get pregnant without knowing who the father is. "If someone fucks up", how do you mean exactly? Like murder of justice? That already happens, yet we endorse the legal system! I don't get the argument, it's very doomsday-predictive but also very generalizing. It is not very concrete, you're not really saying anything of intellectual significance. You could have said "I feel bad about it because I like the freedom of being able to have a child at my will".
All our laws were invented by us. This would be another law. A simple test of financial stability, psychological condition, and aggression / compassion could probably filter out those who abuse their children in various ways, and would make sure no child has to grow up in a home with no furniture. I don't see how that's so bad. No one has defined what that test would actually consist of, which could be an interesting discussion in itself. And if such a test were to be implemented in say my country, and I had a say in it, it wouldn't just be any test. Obviously that's a part of the discussion that was not defined in the original post. What if the tests didn't include any of the things you probably pictured when you made your response, but somehow still managed to pick out bad parents from the bunch? Would
that be such a bad idea? I don't see how having a child is a human right, thought. It's an instinct and a biological function, but so is violence, and we don't allow that either. Having a baby is not a right, but giving a baby a bad life because you wanted one out of selfish reasons, or got one because you have a loose cunt, should be a crime imo. People who grew up with a single parent will maybe say otherwise, but it is a fact that children with two parent figures of opposite sexes have a more stable upbringing, assuming the parents aren't bad people.
But let's not get hung up on two parents. I grew up with two parents, that's not what the discussion is about and I'm making arguments based on my own experience. I'm sure there are other, fairer, better criterias about parent(s)' ability to raise a child that could be used.
I think it's a great idea. Overpopulation will fuck us over eventually anyway. In many contexts we don't consider an individual more important than the collective good, but in this context, for some reason we do. Having a baby = justice?
