It wasn&#x27;t about privacy, it was just buying a truck.  I never said it was about privacy.  Hell, the DMV knew about the truck about 40 minutes after he bought it.  The seller reported it as income[1].  This had nothing to do with privacy or fraud, and his bank wouldn&#x27;t let him write checks for over $5,000 and he sure wasn&#x27;t going to pay some fee for a certified check that the guy selling the truck wasn&#x27;t going to take anyway.<p>We didn&#x27;t see it as a risk.  It was just a bit odd to have 150 $100 bills.  Puts a little weight into the cost of what you&#x27;re going to buy.  Good thing he bought it too as his old truck (which I drove back, that&#x27;s why he brought me not as some security) needed about $3,000 in repairs.  He sold it to a farmer who did the repairs himself.  My friend kept the truck for about 2 decades.<p>1) I remember his receipt pad.  It was styled like something I imagine came out of a Dickens story.  He basically bought wrecks and stuff in garages and restored some or built mods out of others.  Pretty good retirement gig.
