I realized belatedly that my poll omitted a crucial pair of questions: How much do your spatially-close and emotionally-close friendships overlap, and how much would you like them to?

Consider it added and answer it here if you want to. For me the answer is: Enough to be tolerable, but not enough to be perfectly satisfactory. I think I would like maybe a 50% overlap (critical mass, but still excuses to travel). This is basically impossible, though ;).
