Stability is fragile in such systems. Planning in chaotic situations is worthless, since all plans assume a background of stability on which to operate. Money however is merely a form of intermediary, the people, goods, processes throughout the world are all unchanged. By giving supremacy to a mere tool, the real values of the planet are obscured. The value of money in itself is zero.
Feedback comes in two forms.
Negative feedback creates stability, it returns the system to a previous state. Positive feedback creates growth, an exponential change of state. Neither alone is ideal.
