Actually in reference to your query you are partially correct. As best as I can tell there isn't any organization that gives more than simply lip service to the Belt. And it could be argued it never existed. But there is a problem following that train of thought. I believe strongly that in order to select a deserving national champion, particularly at the collegiate level, there needs to be a method behind the madness. Otherwise, anything goes! I would hate to think we could ever reach the point where a person, or group if people unilaterally select a titleist.
Yet that's precisely where we are. Right there. Why is that dangerous? It's an autocracy. Maybe nobody's taught us about autocratic idealogy, but it flies in the face of democracy. What is democracy? Independent thought. Anyway assuming there isn't a Belt you are left to explain the rationale behind the interpretation of what a Championship is. In absentia.
While there us disagreement, and possibly even certain opinions (nothing wrong with an opinion) one is left wondering what matters.
Ultimately we need a Belt to unify the title.
