The sell is downtown brooklyn and its a good sell and would be nice. Convenience, density, transit access, some of the best in the world.
The rub is nyc can’t even do that anymore. How many subway lines came up before 1940 and how many after? What has population growth been like since 1940? All bad on all counts.
We can articulate the solution but we can’t deliver it. Unless you already have this lifestyle you won’t get it. You have to move to where it already is. You can’t expect it to be built for yourself.
