Fair. In my head I consider “dicking around” a part of opportunity loss. Basically sacrificing whatever your definition of fun is with having children and the responsibilities that come with it.
Earlier you said "There’s just too much opportunity loss compared to lower income / less rich countries." I think the lost opportunity value of dicking around would be about equal between wealthy countries and developing countries. You can go to the beach/lake/woods, drink all night, play video games, and binge TV most places in the world. Maybe the wealthy countries would have nicer TVs and more expensive intoxicants, but it's basically the same thing everywhere.
You have more money to dick around with. More money means different types of opportunities, making it less boring. You can keep occupying yourselves with things other than having children.
There’s still some sense of “I should have children to survive in my later years” in developing countries. Not really needed for richer ones where things have established and you can get support in times of needs.
