That's because your argument is false. We have the right to travel by whatever means common that day in age. Try walking down the interstate and see how far you get before you're stop by a man with a badge. You need a license because the State needs revenue and everyone goes along with it.

"CASE #1: "The use of the highway for the purpose of travel and transportation is not a mere privilege, but a common fundamental right of which the public and individuals cannot rightfully be deprived." Chicago Motor Coach v. Chicago, 169 NE 221.
CASE #2: "The right of the citizen to travel upon the public highways and to transport his property thereon, either by carriage or by automobile, is not a mere privilege which a city may prohibit or permit at will, but a common law right which he has under the right to life, liberty, and the pursuit of happiness." Thompson v. Smith, 154 SE 579.
It could not be stated more directly or conclusively that citizens of the states have a common law right to travel, without approval or restriction (license), and that this right is protected under the U.S Constitution.
CASE #3: "The right to travel is a part of the liberty of which the citizen cannot be deprived without due process of law under the Fifth Amendment." Kent v. Dulles, 357 US 116, 125.
CASE #4: "The right to travel is a well-established common right that does not owe its existence to the federal government. It is recognized by the courts as a natural right." Schactman v. Dulles 96 App DC 287, 225 F2d 938, at 941."
But try and make any of these arguments in a kangaroo court.
