What the article says around this equation
An identity in [] does not, by itself, prove there is no advantage anywhere in the physical situation — it proves only that repackaging the energy convention does not manufacture one. The actual question is what it costs, in the distant experimenter’s own currency, to run a real static processor near a real horizon at all, and three costs are not contained in [] 's definition: staying in place, staying cold, and reporting out.
