Right I agree and don’t dismiss that. But I do think those smaller identities appear as a result of material conditions. Community for safety and competition with other groups being a couple of them.

If you eliminate the conditions of needing safety and needing to compete (among others), you eliminate a large part of the need for small area identities. This then reorganises into the larger scale identities of nationality. And this too can (and will) reorganise into international identity when the material conditions that create nationalism are removed.

I am simplifying the process of course but you get what I mean. These structures occur for a reason and removing those reasons can give way to the new structures through a less violent and forceful process.
