We need silly hats. Most human cultures throughout history had hats (or other headwear) that were unique to them, including modern ones. The human eye is naturally drawn to the faces of other humans, and headgear can be a useful shorthand for “who is this and what’s their culture like?” These hats are frequently silly looking. Modern examples include baseball caps, cheese hats, military berets, helmets, cowboy hats, various religious headwear. If you want to stand out as a unified culture, you need your own hat.
