This is exactly what ran through my had reading the bit you quoted above: consistency is king! Try scaling magic. Maybe some people are able to do this. I, personally, am a mere mortal, and that means consistent, clear code is a very powerful tool to me. More so than this "flexibility" the article's author is citing. In fact I would argue that consistency and clarity lend flexibility if you understand what you're doing.
