Well, talk about moving the goal-posts, but you aren't the original poster so I'll give you the benefit of the doubt.

The right to freedom of movement is not really a right if it does not include by all available means.

For example, to say you have the right to walk from the east coast to the west coast but not the right to drive a car (or ride a train/bus/plane - all arguments that have been made post 9/11) means that you de facto do not have the right to travel from the east coast to the west coast because it is impractical for the vast majority of the population to walk it.

I'm sure there are motor vehicle codes that have adopted the language of privilege rather than right if for no other reason than it makes it easier for them to claim that moral authority later on, but that doesn't make it true in the sense of natural law. Government does not grant people privileges because everything the government does comes from the people to begin with.

Driving depends on a huge amount of infrastructure which is provided or controlled by the government, everything from roads to refined fuel. As far as I know you actually can drive a car without a license, if you do that in your private property (e.g. suppose you own a farm or other big property with internal driveways), but not in any public roads. Yeah we pay for the roads, and oil infrastructure and other things with our taxes... it doesn't matter. Google [is driving a privilege], you'll find citations of court decisions, some people have tried to assert their "right to drive" without success.
