Somehow your comment reminds me of the American public education system. It enforces a rigid, highly structured, linear way of thinking. It is very much rules-based. In fact, we spend much of our time learning rules vs. how to think.
The notion that a single construction system is better fits with this. It expresses a desire to eliminate variables, clearly define the rules, create a very tight system, etc. But, I think the statement that it forces you into more creative problem solving is exactly backwards. It may encourage resourcefulness, which entails some creativity to be sure. But, it asks "what can be done within a confined, limited space?" vs. "what can be done if there were virtually no limits?"
As Americans, I think we need to improve upon the latter style of thinking. It is the source of true invention and creativity vs. mere innovation or improvement upon existing creations as encouraged by the former.
Maybe this is, in part, why we see so many copycat startups and businesses built upon some iterative improvement to an existing process or idea. Instead of always asking, "how can we do something slightly better?", we need to ask more, "what else can we do?"
