Think about all other traditional hats associated with a particular tribe, the Laotian wear lampshades to keep the sun off, the aussies wear cork hats to keep the flies away, the eskimos wear fur hats to keep warm. All have a practical use.
But the kippah has no practical use, it is entirely for show. It's only function is to broadcast how you are in a position of power or have a job inside the institutions, so you don't need protection from the elements while toiling outside all day.
