need? what does need have to do with it? and what do you mean by real?
some of those people were people who wanted to be able to purchase firearms and have them shipped directly to their homes, not pay an extra $10-$50 to have it delivered to a dealer.
many of them ran their firearms business as a home based business. alot of them got jacked in various ways for it, so they dropped their license. others decided that the intrusion, and all the hoops they had to jump thru weren't worth it.
btw. do you NEED a drivers license? why don't you take a cab or a bus or walk or ride a bike? are you a real driver? do you drive a truck or a bus?
