Just like a quality architect wouldn't want to build a house

As someone who actually went to school for that before tech - architects don't build houses.

You know who does, in the US? Del Webb and other massive builders, who give the lowest common denominator slop because that's what the economics of the market demand, and the profits of the funding require.

The problem is almost always the power relationships behind the tools - it's not that the plans are done by CAD or hand that matter.
