Okay, let me ask this in a different way:
Do you think those hundreds of kids who go to the Orange Bowl Regatta in Miami every winter are doing it because they are thinking about maybe someday going to the Olympics?
Or would those kids go to that regatta even if sailing were NOT in the Olympics?

And do youth sailors sign up to participate in the U.S. Youth Multihull Championship because there is a multihull in the Olympics? Or do they do it because they want to win the national championship and go on to the world championship? If they knew sailing was not in the Olympics or a multihull was not in the Olympics, would they just say, to heck with it and find a sport that IS in the Olympics?

Does an adult who is choosing a sport to get into in mid life make his decision based upon what sports are in the Olympics?
