Your link doesn't work,

Newly built density, to the point of diminishing returns is plenty efficient - that is however not what is typically being built. Introducing and maintaining and continually developing density in intensely developed urban areas is catastrophically expensive.

I don't know what your link says because it won't open - but every argument I have seen that claims urban infrastructure costs are favourable is based on a wholly unrealistic static situation that just isn't found in urban areas that aren't completely moribund.
