I don't think that's it, at least for public buildings like churches, theaters, town halls, museums, and so on. After all, veto power doesn't prevent awful buildings like the Walkie Talkie building[1] from being built, as long as they conform to the bland, in vogue architectural tastes. It's the cult of postmodernism, stripping away visually interesting features, even though humans gravitate to older buildings despite the "form over function" blind cult thinking. This has dominated architecture for the past few decades. Many older buildings are simply built with many intricate visual details that are architectural heresy nowadays. As mentioned, there was a briliant article and HN discussion on this recent-ish, I just cannot dig it up.
EDIT: This is the article, "Why You Hate Contemporary Architecture":
Today your design has to be approved by many different people with veto power.
Back in the day, you built what you wanted on your property.
