I generally agree with this, but I want to add another thing that I feel is easily overlooked in both the groups you listed and your post: having men who'd make women comfortable having kids.

The alpha-bro intimidation, casual assault/misogyny, disregard for mothers' careers, and lack of community don't exactly scream "great time to have a baby" (I'm not even going to touch the current topic dominating the news). While some of these things are not unique to our time, they compound quite negatively in an era of unaffordability and social immobility. Additionally, everyone acknowledges "it takes a village," but there aren't very many who are trying to be villagers. When's the last time most of us here spent time with our neighbors?

All the approaches to the fertility problem seem to come from men or deeply conservative women who parrot men. That sounds like an echo chamber to me.
