After all, the most important discoveries in science since Boltzmann or even Maxwell have been based on statistical mechanics, mapping likelyhoods and probabilities. And the most virulent skeptics of GCC re-iterate that there is "no definitive proof!" , when GCC arguments have always been closer to actuarial estimates than some kind of Euclidian construct.

Part of what you see with some big firms leaving the Chamber of Commerce over this issue is that if you are creating models of the future you need to consider the probabilities and eventualities, which leads you to look at the regulatory landscape differently. It also results in different valuations on entities across a wide spectrum of the markets. That's the part of all of this that hasn't gotten enough play from the investment community.
