Markets and the externality overlay
The market interior is kept intact: it clears allocation and carries the profit signal, and Axiacracy does not override it. What it does badly, ignore the harm a transaction imposes on axes the price cannot see, is corrected by an overlay, not by seizing the wheel.
The overlay is a multidimensional Pigouvian charge: a wedge on a live price where the harmed good is traded, gated by a market-still-clears test, and framed honestly as a liability rather than a "true price." Prices in, quantities out, the state sets the price a factor faces and never dictates the quantity it chooses. What the market does well it keeps; what it is blind to, the overlay makes visible and payable.
What it means
Keep the market; add an overlay for what it cannot see. A factory dumps effluent into a river: the market price of its goods includes the labour and steel but not the river it poisons, that cost lands on everyone downstream. The externality overlay puts a charge equal to the measured harm on the ecological and health axes, as a wedge on the market price. The polluter now pays for the harm, the price of its goods rises to tell the truth, and, crucially, the market still clears: firms still choose what and how much to produce. Contrast a ban or a quota, which dictates the quantity and needs knowledge no regulator has. Carbon pricing and congestion charges are this idea in daily use.
Why Axiacracy needs it
The market is superb at allocation and blind to what it does not price. Externalities are not a quirk but the market's structural failure, and left unpriced they compound until they wreck the very substrate the economy stands on. This § exists to repair that one great blindness without seizing the wheel, the single cleanest expression of "corrects but does not direct."
Compared with other approaches
It sides with Pigou (tax the harm) over pure Coase (let the parties bargain it away), because the harmed are usually diffuse and cannot bargain. Between the two carbon instruments it prefers a price wedge to a quantity cap-and-trade, prices in, quantities out. The discipline that the charge must be a wedge on a real clearing price, not an invented one, is Mises's (Mises). The governing posture behind it is §6; the rent it borders on is §12.
