Your roads are not free. Your government delivered roads are funded by stolen money. The gun at the toll is at least honest in that hes collecting money for a specific service and you can choose to take non-toll roads, train or fly. The money taken in taxation to fund your roads (so you dont have to face the realism of the toll) is less honest as you have no idea how its being used. You do not have the right to freedom of movement if it means I'm forced to pay for it.
