In order to drive, we must have a license. We must have a license to own and operate a business. We must have a license to go fly-fishing. We have to have a license to serve liquor in our establishments. We must have a license to operate an 18-wheeled semi. We must have a license to teach children the basics of education. We do not need a license to produce offspring. Go figure.
