there's probably a healthy middle ground between "all women should be permanently pregnant" and "no kids ever". Like, building a world where we can sustainably support the continuation of humankind, while also leaving room for people wanting to go childless or have a big family, is not the same as wanting to control who gets how many children. We also have to think about the fact that the last few hundred years have been very chaotic and rapidly changing and it's very hard to determine where the """natural""" ( I know natural is not a thing really) birthrate should be in the context of a normal, non fucked society existing in a cooperative global environment because we haven't seen one of those yet.
