Why is it a goal to populate the world to a maximal amount? Yeah, we could make room for more people by restricting the lives of the others... but why? Why not identify a comfortable, sustainable level, and keep the level there? The earth is not crying out for more people to be on it, and no societal problems are solved by adding more (quite the opposite). Being told you can only have 2 kids max is less dystopian than outcomes from overpopulation.
