I was replying to specific point that you were making about fitness value of riding fixed gear bikes. However, I feel your pain

and will give you my two basis points on the utility value of fixed-gear bikes.
Utility biking is vast - one could imagine applications where a fixed gear bike might make sense. While you would not want a fixed-gear bike for delivering pizza, you might like one for riding as a messenger in Manhattan. Ability to track-stand with ease at the lights, simplicity in terms of repair and low(er) theft probabiity would be the reasons.
