"Possible" and "beneficial" are separate questions entirely. The whole point of government is to be a central authority. That's the DMV's entire job: to be a central authority for driver's licenses and vehicle titles. Their database isn't open for everybody to modify, and it also shouldn't be. It also shouldn't be open for everybody to read, because we have a right to privacy. What benefit does the DMV get from hosting its records on a blockchain? And what happens if that blockchain stops attracting miners? Does the DMV have to mine it? Does the price of mining rigs start to affect how much it costs to register your car? What happens if they get hit by a 51% attack? Your average Californian is definitely not a crypto user, and doesn't have a digital wallet. One in twenty don't even speak English. What happens when somebody loses their private key? If you have to keep those keys in a conventional database, then a blockchain makes zero sense except as a money-waster. There is nothing wrong with them just running a regular database, with normal SRE stuff like backups and replication. The California DMV has a lot of problems. But "how do we store records?" isn't one of them.
