The indirectness and lack of strategic focus of the implementation of its policies. In other words its policies only reach the individual by first going through the system when the system’s normal operation is in a state of dynamic disequilibrium and so they merely re-initiate its (the system’s) problem. It also is unconscious of the best and most appropriate moment to effect policy which is at a/the very terminal ending points in the economy where production becomes consumption. That way the effect of monetary policy actually addresses the correct problem and, assuming the policy is the correct solution to the problem [the direct monetary elimination of individual monetary scarcity and excess/additional costs-prices] and a monetary authority is mandated to do these actions with cost free money,  no agent on either side of the production/consumption duality can be harmed.
