Rewilding the people seems to be the important bit. Cities, by nature, are CAFOs full of domesticated animals. Allowing people enough resources to build wild human tribal areas (your meatpacking district?) seems to be at least part of our own homeless problem in the US. We have homogenized and regulated away many options until no people are actually usefully involved in their places. Habitat for Humanity tries to reverse it to some degree, but it's just a trickle within a zoned desert.
