Why would the MCO be his “property”? He never actually had it, did he? If the dealership sent the MCO to the state DMV and got back a title, and then sold the car to your friend and gave him the title, he never gained ownership of the MCO in the first place.
Cranks often have strange ideas about ownership and laws and money. Like, that Federal Reserve Notes aren’t “really” money. But money is just a particular kind of good that you can exchange easily for goods and services. Cigarettes, cacao beans, cowrie shells, and cows have been used as money at various times and places, and those things really were real money, because they really could be exchanged for goods and services. And a Federal Reserve Note really is real money because if you take one to the 7-11, the Pakistani guy behind the counter will take it in exchange for a bag of chips. And if someday the 7-11 guy refuses your FRN and demands gold or silver coins, then your FRN is no longer a form of money, it’s just a piece of paper with fancy pictures.
So what is the title of a car anyway? Magic? No, it’s just a piece of paper with some words written on it. It is a record of who owns what. If I sell you a car, and some random guy in a basement office types up a piece of paper that declares that random guy to be the real owner of the car, does that piece of paper make him the owner of the car? No it doesn’t, unless he can take that piece of paper to a judge, and use it to convince a judge that he owns the car, and the judge can convince a cop to go over to your house and take the car from your driveway and give it to the random guy.
So in what way does that magical piece of paper make the State the “true owner” of the car? Does it mean that a guy from the DMV can walk over to your house, hop in the driver’s seat, and take the car back to the DMV lot? Does it mean the DMV guy can sell your car to some other random guy?
In a state of nature there is no such thing as ownership. If Og and Thag the cavemen are arguing over who owns a particular shiny rock, and Thag smacks Og on the head and takes the rock, who owns the rock? If Og waits until Thag is sleeping and smacks Thag on the head and takes the rock, who owns the rock?
Ownership as a concept only applies when Og and Thag can appeal to third parties to settle their dispute. If it’s just a case of who’s bigger and stronger and trickier, then ownership is moot. But if Torg and Gack agree with Og that Og should have the rock, and they’re willing to help Og defend the rock against Thag, well, now we’re talking ownership. Og owns the rock to the extent that Torg and Gack agree he owns the rock.
So back to the car. The auto manufacturer builds the car. They own the car. The sell the car to the dealer. The dealer owns the car. The dealer sells the car to your friend. Your friend owns the car. In what sense does the state “really” own the car? Because of a magic piece of paper? No, the piece of paper doesn’t make the manufacturer or the dealer or your friend own the car, the pieces of paper are just records so that when the three of you are smacking each other on the head over who gets the car, a passing cop can read the piece of paper and figure out who’s telling the truth. In no case will the cop take a look at the Manufacturers Certificate of Origin on file down at the DMV, and conclude that the DMV really owns the car, and turn the car over to the clerks at the DMV.
Since in no case will the cops and the judges turn the car over to the DMV as the real owners of the car, then it’s nonsensical to claim that the DMV is the real owner of the car. You don’t have to register your car with the state and get license plates because the state owns your car, you need to register your car and have a license plate before the state will allow you to drive your car on the public roads. As long as you stay off the public roads you have no need for a driver’s license, or a license plate, or a registration.
