As the title states, you do not need a license to drive your personal vehicle for private use. The law states you are only required to have a licence for commerce. This also includes license plates, inspection and registration. Don't take my word for it, do your research.
I believe in most states as long as you are on "Private Property" you do not need to be licensed to operate a vehicle.
As soon as it touches a "Public" road you better have one.
Similar to our seat belt law. Farm equipment does not require the use of a seat belt. A truck can easily be registered as "Farm Equipment". If on the public road going to the grocery store do you need a seat belt if driving a truck registered as "farm equipment". It's a good idea as most law enforcement may not see it as farm equipment since it is not a tractor.
