The state, and that's each individual state, does lots of things that aren't legitimate. We need to end those activities, the safest method of doing that is to remove their power to do so.
For example, here in SC, the State Law Enforcement Division gets to lobby the state legislature on restrictions and requirements for concealed carry of firearms, and most other weapons laws. Should we continue to permit such an obvious conflict of interest by a state agency? I posit that we should not.
Driver's licenses got a good thrashing at the hands of the US government via the national ID legislation; that is to say, it woke many people up to the real threat that Driver's licenses pose to people.
It's a good idea to actually study the history of both titling and licensing cars, and the beginning of the concept of the driver's license. All of them are 20th century constructs for the most part, and doing without any of them are mala prohibitum violations, most of which are disgusting restrictions on personal freedom that need to go extinct.
