Excellent point.

Longnow.org has a lot of material about the resilience of cities over very long time scales (like, millennia).

Here’s an example on the resilience of cities versus corporations: https://longnow.org/seminars/02011/jul/25/why-cities-keep-gr...

Another example, from a longnow podcast, is the tendency of people to think of themselves as citizens of a particular city (I’m from San Francisco, I’m from Venice, I’m from Helsinki), perhaps even more so than a state/province or a nationality in some cases.
