Exactly ^ ^ That's why overpopulation is technically a non-issue.

You have to remember the fertility rate is 100% in Selforge City, and no parent can possibly keep up with that, unless they have unlimited ubiquity like Lawrence and Seira, which is not the case for citizens to preserve their humanity. An alternative system was thus needed to ensure everything still works out for everyone, which is the purpose of the Legacy Heaven.

Actually, no one can take care of a child better than the Silver Sisters, as they are basically altruism and competence personified, just like Seira they all descend from, so the children raised by them are most certainly no less happier than those raised by their original mother.

The Legacy Heaven is not a daycare center, it is a complete and independent alternative to Selforge City, where children "all enjoy the same privileges as Selforge citizens, except in a more immersive, decentralized and diversified way, divided into many cultures and societies over immense territories in myriads of worlds, forming an ever-expanding mosaic of ever-changing realms."

In short, they live their own happy life in their own happy world with their own happy family.
