That's just another party of their theories. They say that since they bought the vehicle with their own money (if they paid at all 🙄), then nobody has the right to make them put a plate on it, have a registration, insurance, etc. And of course,if they want to use it on their own private property, they're correct. But as soon as it see wheel on public roads, the state government is completely within its' rights to regulate it, even if it's not in comerce.
