I think you are missing a couple of things. In this comment I will equate "Rug Market" with "Ready, Fire, Aim" and "Cathedral" with "4 Year Plan".

Secondly, the "Rug Market" beats the "Cathedral" when bad software is more profitable than good software. Google for "Worse Is Better" and "The Innovator's Dilemma". Sad but true.
