Can you cite a couple of cases? 
You are wrong about this. The US Supreme Court has repeatedly upheld a state's authority to require that all motorists be licensed, be insured, etc.

Well, we're starting to get into that gray area where lawyers make money, and scumbag sexual predators can argue about the definition of the word "is".
Just because a state can require that all motorists be licensed, it doesn't mean that everyone has to have a driver's license. Some people have no need for a driver's license, because they don't drive. That doesn't make them criminals.
Personally, I think this guy was looking for an excuse to try to pull some stunt like this. I think he wants media attention.
