Classic slam dunk on economists, except I think it's a bit of a miss. They're a classic scapegoat and punching bag but there's tons of economics research on community.

Saying economics doesn’t model community is a bit like saying physics doesn’t model color because some models ignore wavelength variation. It depends which models you’re looking at and what their purpose is. There is substantial economic research on: Social capital (e.g., Putnam, though he’s political science adjacent; economists like Glaeser formalize it) Network effects and network structure Repeated games and reputation Religious participation and club goods (Iannaccone’s work is central here) Identity economics (Akerlof & Kranton) Trust and informal institutions Household bargaining models Matching theory, where who you match with specifically matters

I think the fact that communities are not fungible is frankly obvious. Fact is communities do die, and sometimes there are long run benefits to consider.

The challenge is actually nurturing and valuing community which this post doesn't actually grapple with.

E.g. the problem with Robert Moses wasn't just development. It was the style of development which was inherently anti-community. Nurturing a community requires common space where people bump into each other harmlessly. Highways dividing neighbourhoods, for people in their private cars to get to neighbourhoods with no commercial life and large setbacks between homes.

It's not that Robert Moses didn't realize community isn't fungible. It's either that he didn't realize how bad it would be for community or that he just didn't value community in the first place.
