Yes, I read the article. All the handwaving about maybe land on the fringe... but maybe that would actually be more expensive because of land use restrictions... and utilities would have to happen somehow but not clear about the costs.
>Affordable housing requires affordable land. Big cities almost by definition do not have affordable land, therefore the housing will never be affordable in the way the author is asserting.
I agree. My assumption was that, given this context, he was talking about the outlying areas of cities people were interested in. Of course, otherwise, land prices are not the issue and housing construction prices aren't really the issue either.
