It’s all tribes.

Not ideologies.
Not countries.
Not borders.
Not even leaders.

Just tribes.

Look at the flip on free speech and free markets. Ideology only matters if benefits your tribe.

Look at the social networks, conferences, and crypto tribes that cross borders. Are you hanging with your physical neighbors or your tribesmen?

Look at the decentralized order of tribes. Is that a single king-like leader?

A better term than “nation state” is “tribe state”, which more clearly conveys what the term “nation” used to mean.

A nation state is a single-tribe state.

That’s what it meant historically. If you had multiple large tribes under one government, that was a multiethnic empire, not a nation state.

I see your point. It’s well reflected in the difficulty nation states seem to have with governing different tribes. 

And there’s an inherent concern here. Nations are largely geographical in nature. And tribes can’t be characterised primarily by proximity anymore. 

To me, that does describe the problem nicely.
