I agree as well, but this wheel is exactly what the mid-school was all about; Change, and new outside of the box ideas.
Were 72 spokes ever needed? NO. But the simple fact that people were trying to think ahead and do something new has lead to all of the great advancements in the BMX world that we are still seeing today. Flangeless hubs for example. Will they ever take off? I doubt it, but it's another new idea just like the 72 spoke wheel was BITD. BTW, Nice find!
