The unknowable costs

 The inherent losses in government monetary base. Only discovered ex post, the unhedgeables, always white noise and assumed to be bound, ex ante, by optimum congestion pricing. So we all have to put our faith in the hypothetical automated pricing bot, the auctioneer. It gives us the bill, in the collective, and we have no one to blame but fixed government structure.  Who pays? We all do, this is coinage power, the treasuries allotment of double spending. There is no optimum legal tax for this. All the txes down the chain are better spent hedging the knowables.

It is less than 1.5% per year, likely below 1%. A good proxy for hedgable is a third of the federal budget, or more than five times the unknowables. But the hedgeables are more accurate the more liquid the bets. If we use earmark hedging, the unknowables will jump, we lose granularity.
