Fair enough, but if a degree doesn't guarantee competence, how could a license? CS programmes everywhere are getting blasted by the industry for not "producing" graduates that meet their requirements, therefore it's reasonable to assume that a certification process would suffer the same fate. How could such a process meet the demands of a rapidly changing industry where different players have completely different requirements, where the language-du-jour is constantly changing, where best practices are outdated in a few years, and where the only way to survive is to constantly educate yourself? I don't see how an IT license could lead to anything but a sort of tax on corporate IT companies that wish to do business with the government.
