We clearly don’t support anything now, so this argument seems to be in the same category of wishful thinking. These questions could be asked if the current system passed the tests. People already have 0-1 kids. They gather in packs to live in cardboard boxes with nominal utilities. A system with free agents is very prone to painting itself into a corner, it’s unstable by design. One of the issues that we have is that on the brink of catastrophe we are still asking ourselves whether the less carastrophic measures are ethical. But times of “we do what we want” end with the last decent square mile allocated for crops and housing. We’re at such hard physical limits for the first time, so it will take a couple of world wars to figure out new rules, I guess.
