Does anyone know of any place where John Q. Citizen can walk in off the street
and buy an 80% lower for cash without providing name, rank, and serial number?

I've seen lots of 80% lowers sold at gun shows, no way of identifying purchasers. Just park a few blocks away and walk, so the ATF doesn't record your license plate. ;-)
