Writer of the piece is assuming if you cut the social safety net and welfare state of pensions, people will instead choose to have kids as a safety net. That is not a bet I would make.

My hot take is women will simply form communities to take care of each other until death, and I'm specific about women because they are the ones opting out of having children. They will not be concerned by such an attempt.
