Are you on something?
Your rambling barely makes sense, but at least I understood the last paragraph enough to answer.
As long as I have a secure job and am set up for a decent retirement, both of which I have, I see no reason not to keep my current San Diego residence as my home base until I die. I do have an itch to travel though, and may spend considerable time abroad for that reason once I retire. If the US destroys itself though, then going back to to the countries of my European heritage wouldn’t be a bad option. It would take some getting used to, but I’d manage.
