I don't think this is the issue. As the article talks about, architecture is shaped by regulation. Of course, you can usually construct exotic buildings if you have the money and the will to do so, but building codes explicitly approving a specific design will create a monoculture. That's not to say this is necessarily bad. It allows for safety and environmental standards in buildings people are able to afford because of minimal marginal compliance cost.
