There was a TED talk regarding this video.

Derek Sivers: How to start a movement | Video on TED.com

Knave, I think you're misunderstanding the point, people WERE pointing and thinking look at that prat. He was just a prat until others joined him. When we go out on a limb alone like that we NEED outside support and acceptance from a few people to gain acceptance from the wider crowd. He doesn't gain value from simply being the only person with confidence enough to dance alone, he gains his value from the others that join him, otherwise he's just a lone crazy person. It's much like breakaway scientists claiming the world is round, they're just crazy people until they get support from others.

As I said, TED talk, watch it.
