No I am not missing that I just think that JIT done right (no true scottsman) doesn't require stable flow. At best it needs predictable flows and in the current economic system where a lot of information is lost at the company border => the only way to ensure predictability in our current system is have steadyness if things pass company borders.
If we are making statements about how our economic system ought to be it we should consider either flexible pricing that actually reflects information at the company border (with all the Pareto front guarantees that can bring us) or cross company optimization of the economy (providing better guarantees).
