It’s such a cool idea, I can’t wait to see it happen.
I mean, a tiny humanity which has successfully spread out across the solar system but regularly loses significant fractions of its population in stupid wars and cases of ecological/arcological collapse seems plausible to me. But hey, if you’re part of the 1% (1% of the remaining seventy million humans alive) things are great! Who knows, maybe my descendants will be scrabbling to survive in the abandoned wreck of the lunar colonies, jealous of the space-serfs in the Uranus arcology who have actual breathable air for the low, low price of seventy hours of work a week!
Who am I kidding. My line will end with the collapse of earth’s current climate and political order (and it might end with me, considering the speed of things).
