Actually, if it works as claimed it may not be all that crazy. Properly clipped to your tightened belt it shouldn't drag your pants down, I've used similarly attached gun holsters and they work just fine, though something with say belt loops gives me more confidence that I'm not going to chase my gun as it slides across the pavement if I run or move fast. And it should allow you more comfortable movement than a camera swinging from a neckstrap. It's probably a comfortable way to carry.
