Re: the driver's license Right vs. Privilege debate, AFAIK no US state requires a driver's license or vehicle registration for bicycling on public roads. IOW if you philosophically object to the idea of obtaining a gov't license or paying a tax in order to exercise a right, feel free to pedal away.
Additionally, AFAIK you cannot be charged with a DUI while riding a bicycle in most states, although you may be charged with public intoxication, reckless driving, and/or obstruction of traffic.
I suppose bicycles are the vehicular equivalent of black powder muzzleloaders.
