It's perhaps a little ambiguous, but I understood the comment as arguing the exact opposite. I interpreted "overdevelopment" to basically mean the kind of sprawl explainted here: https://www.strongtowns.org/journal/2017/1/9/the-real-reason... ...where cities expand horizontally for short-term tax revenue gains/federal grants while accruing long-term infrastructure costs that their tax bases can't pay.

As George Carlin said, The Earth is fine. The Earth ain't goin nowhere. We're all gonna die.
