You're fine. I wasn't necessarily putting forth a specific solution here, just looking to hear thoughts of others in this area.
I do agree that the limits of our resources could drive to something, whether that be centralized or the push to keep the individual nations/societies/or whatever form a group would take. However with the new research and potential profits available with asteroid (and moon) mining this pressure might get extended, maybe indefinitely.
It'll be interesting to see how it ends change (or not) as time goes on.
