Biggest problems with "Abundance" are:

1) Somehow he decided euclidean zoning was a leftist project. Most leftists and environmentalists I've ever known hate euclidean zoning and this includes many urban planners. Euclidean zoning exists pretty much because property owners want to be able to exclude nearby land uses. It's fundamentally conservative, especially when the goal is to enforce limited housing density.

2) Setting up euclidean zoning as the main whipping boy and then saying "and also air quality regulations are basically the same thing" is a form of straw-manning the stuff he's arguing against.

3) He sets up a dichotomy between California and Texas ignoring that a lot of California's problems are conservative (downzoning, prop 13) and also ignoring the weaknesses in the Texas model including corporations running roughshod over locals (https://www.youtube.com/watch?v=m7_WDzPyoqU) a fragile power grid, huge flooding problems etc. It's possible to look at quality of life metrics and see that Texas is doing quite badly. Also, you had the whole tech moving to Austin thing that already fizzled out.

4) He set up developers as the heroes in the story and apparently got a lot of his info from private equity ride-alongs. He ignores that developers are also often land speculators and are in favor of blocking competitors projects and downzoning areas to keep land value high.

Basically Abundance is a way for Ezra Klein and his fellow travelers to repackage Clinton-era triangulation and Obama-era neoliberalism as something completely new, so the party can carry on with its pro-donor agenda and ignore why they keep losing. That's also the reason why it was astroturfed into every left media space with a massive marketing budget.
