A LICENSE is for business purposes
The "driver license" is issued to people who engage in commerce using the streets and highways. A LICENSE is for business purposes. "Driving" is a privilege because it's regulated business activity. The term "traffic" is another word for "commerce". You can not be FORCED to ask your servants for permission and pay an annual rent to use your car to go to your place of worship or to the store to buy food and clothing. You have the unalienable right to travel for noncommercial household purposes to acquire the necessities of life or for your enjoyment. See your State Constitution.
A "driver" is someone who gets some form of compensation to go somewhere ie: Cab DRIVER, Tow Truck DRIVER, UPS DRIVER. These people get paid to do the act. If you don't get paid/compensated then you aren't properly identified as a "driver". Don't use the common definition, use the "legal" definition because that's the definition used by the State Legislature. Driver is someone who gets paid.
Understand what a "LICENSE" is for and you'll understand what the DMV regulates. If you don't sell liquor then you aren't REQUIRED to apply for a liquor LICENSE. If you don't sell flowers then you aren't REQUIRED to apply for a LICENSE because you're not a florist.
You aren't required to have a LICENSE for non-commercial travel.
