"Oh, at the moment, we don't have any technical definition of what fairness is, really, just this one permutation-based formula I gave you which I claimed might have something to do with fair answers, and four particular properties that might seem intuitively appealing for a fair solution.  So at present, we could at best say that the permutation-based formula doesn't split rewards evenly; and that splitting rewards evenly violates the intuitively appealing notion that zero marginal production should receive zero reward."
