I have a libertarian bent. However...

Would you ride a bus driven by an unlicensed driver?

Would you like an 18-wheeler with an unlicensed driver in the lane next to your kids while they are on the school bus?

Would you fly in a plane with an unlicensed pilot?

How about surgery performed by an unlicensed surgeon?

I spent quite a few hours directing traffic this past weekend. If anything, licensing needs to be stricter than it is.
