I think that the major reason for the authors call for regulations similar to car use on motorways (the driving license, tests and so on) Is an old school perception of a computer and the Internet as some kind of device (a car) of limited use (transportation). A computer is much more universal tool. And in my opinion, the Internet is more like a city, (or better a world itself ) than the highway. As people were able to live with dangers of the world outside, they will learn it online. Although I agree that education is essentially needed in first place, but not going hand-in hand with licenses.
