There Can Be No Calculation Problem in the Evenly Rotating Economy (ERE) Because No Calculation There Is Necessary

The proof-by-listing-of-mathematical-equations is no proof at all. It applies, at best, only to the evenly rotating economy. Obviously, our whole discussion of the calculation problem applies to the real world and to it only. There can be no calculation problem in the ERE because no calculation there is necessary. Obviously, there is no need to calculate profits and losses when all future data are known from the beginning and where there are no profits and losses.  In the ERE, the best allocation of resources proceeds automatically. For Barone to demonstrate that the calculation difficulty does not exist in the ERE is not a solution; it is simply a mathematical belaboring of the obvious. The difficulty of calculation applies to the real world only.
