There is already one contradiction in there - you say planning would have to act quickly and planning happens for extended periods. That is of course not mutually exclusive because you could usually do some longer term planning and resort to quick interventions when needed. But could you really isolate those? Wouldn't quick interventions in one area not likely also have indirect effects on other areas making at least some smaller adjustments necessary? This looks to me like you would become pretty busy doing quick interventions and propagating the ripples through the rest of the plan at which point you are back where you started without any longer term planing. It seems to me that any form of longer term planning incurs a cost by not being able to react in a timely manner, effects propagating asynchronously and as fast as possible in markets would propagate way slower over a couple of planning iterations because they are unnecessarily forced into lockstep.
