You need a license to use the public roads. And you have an immediate problem if they take your license in that you now need to get your vehicle AND you home without you behind the wheel, because there’s cops right there that know you don’t have a license (because they took it). Yeah later you can get around with a suspended license, just don’t get pulled over. I knew a guy who spent 5 or 6 years without a license, because he wasn’t smart enough to not do other illegal things while driving on that lack of license, so he’d get tickets for both his moving violation AND driving on a suspended license, which restarted his suspension clock. Turned into a very expensive hobby for him.
You don't need one if you don't ask for one.
