Make a billion dollars with indifference curves.

 Along the red line you are indifferent to having more of the one good over the other. (Rasberry or chocalate is fine).

I have a retail trick.   Get a map of a lerge city and lay it on the table.  Then get a string, thumbtack and sharpened pencil to make indifferent.  The idea is to find a radius that just captured a neighborhood for which you are indifferent to path.  Any path from the thumbtack to the boundary gets you through the same number of houses.

Your thumbtack, wherever it is on the map is a point of symmetry, all travel to and from the neighborhood through the intersection of your thumbtack can measure path as a distance to you thumbtack. 

Now you want to find the complement of the neighborhood, the work places. Take your string and drqaw an arcf through the edge of the factories, try to capture the majority in an enclosing arc.

&-11 planners do this, as do WalMarters, they find the constricting path in the customer flow and encourage them to stop and pick up a few items.

Trees do the same thing, in reverse. They grow a root structure down and a branch structure up such that the flow is optimally constricting at the trunk.

This is all about whitening, whitening in graph space.  But it brings up a point, stores and homeowners have been doing this in Southern California since the beginning (1950). Any attempt to split up the co-agglomeration will result in huge quantization noise, the layers of packing are deep.

Home owners know this, they know the cost of a convenient 7-11, and they prefer to pay it if they get more time at home. Split roll property taxes are a nightmare for California, especially suburban southern California.

Gavin don't want that battle or that risk.    The lifestyle has been refined, filled in, complexified, and layered; it is inbred in California, like a stone down there.  This is a battle Gavin does not want, nor Garcetti.

I think we are in a frigged situation, one of those meeting of the elders.
