Depends what 'license' refers to. I have a passport, which is like a license to go abroad, eh? National insurance card, something of a license to work, yes? I'm also the license (copyright and creative commons) holder of my artwork and literary work.
Anyway, yes, I do know you actually mean a driver's license. I don't have one and don't want one, I prefer cycling to where I want to get. Can't exactly take a car along the shortcut through the park into town can I?... Well, if my dad was still working for the borough council (and if they didn't concrete the barriers to the ground by one of the main gates), I actually would be able to, but you get the point. xD
But... sigh... it will be useful in the inevitable event that I'll be required to travel long distances to out of town shops and in doing errands for my parents and friends.
