I realize he is arguing for that but I think its pretty silly to have the chart there showing the correlation if so. He does address the point I made in the article but I think he dismisses it too fast without much evidence.

I suppose to expound on my point more - the graph is by people not housing units. Presumably if a cheap city, like Detroit, had a bunch of unused units the graph would not credit it for the built-in density because if its not being used.
