this is a good counter argument. I ask the same question about the individual vs city vs state vs nation scales. though I dont think you agree it applies.
My main qualm with the hyper-individual sovereignty angle is that, basically, it assumes that a society can exist without ANY identity groups whatsoever. Like not even a family.
think the issue now is that with the internet, identity groups are no longer just those around u. BCH group is spread world wide but must still conform to (arbitrary?) geographic lines
