Unless you’re wild camping, campsites have addresses. So do marinas where a ship would need to be docked more or less regularly to establish residency.
As for being a nomad, you don’t need a driver’s license or any kind of ID to wander if you’re willing to sleep rough. If you want to drive on public roadways though, you better have a primary address where the courts can send someone if you kill someone in a traffic accident and bail.
Docking is expensive, so no. It's also only needed once per 5 years or so for maintenance.
Government fining you a ticket doesn't mean your address has to be on the drivers license. They could register the number plate to an SSN for instance.
Did you skip my last sentence? A traffic ticket is not the worst thing you can do in an automobile. And not everyone eligible for a drivers license will have an SSN.
Laws of the government can't override laws of physics. If you don't have a place where you can receive mail, do they just arrest you or what? Do they assign a PO box to you?
So much for "land of the free".
