You live in a very strange country, in the UK your dad would have had his car taken away from him and crushed... and if he repeatedly found other cars to drive without a license he would probably end up in prison.
I don't know how many they actually crushed, but it was some.
My dad has gone to jail for driving without a license before, but he'll go out driving when he gets out of jail. But usually his lawyer finds some sort of technically that gets him out of major trouble. I don't know the exact details, I try to ignore him as much as possible.
Other family members I know who have lost their license, it's stopped extractly zero people from driving. If you don't care about the other laws enough to get caught breaking them enough to lose your license you don't care about breaking "no driving without a license" law.
What is stopping someone who loses their license from just driving anyway? They've already shown not to give a shit, so they'll continue driving without a license.
My dad lost his license many years ago and never stopped driving. He gets arrested once in a while, doesn't stop him.
