Clearwater doesn't grok markets very well if he believes this. What
Clearwater neglects is that the market itself is a communicating agent.
Therefore, between any two parties A and B in a market, there is a
communication channel involving at most two steps.
To illustrate: by varying my demand, given knowledge of the market
resolution algorithm, I can predictably induce rebalancing requests that
will be delivered to you. Two parties collaborating in this way have a
strikingly effective means of communication.
