He didn't say required. However, in a galaxy far far away, in a time far before we were born... people had their shit together and would self regulate certain aspects of commerce. You can see it today when you buy a car and the salesman shows you where the windshield wiper control is.
It wouldn't have to be regulated, because the seller would show you as a courtesy, and a matter of service. The purchaser, as a conscientious person wouldask for it if it wasn't offered, or would find someone with the knowledge to show them the ropes.
No .gov needed or welcome.
Exactly, you come into my store to purchase a firearm. You don't point the muzzle at me, keep your finger off the trigger, refuse to handle firearm if handed unchecked and am able able to tell the difference between a 30-06 and a 308 or 38 and 357. There are many things in life we all have a way of knowing whether or not another person is a knowing individual or not, it doesn't take a license.
On another note, since the government and the 50 states ( or is it 57 ) have damn near tried every law in the world and have seen they do nothing to prevent crime or stop criminals from obtaining firearms, why not just give the true meaning our forefathers intended on the implementation of the right to bear arms a fair shake and let open carry, no licensing, no permits of guns a fair chance and lets see what effect that has on everyday life. I honestly believe crime will plummet and society would become a much more civil place. This includes everything from 50 cal machine guns right down to mouseguns. Think of the money saved when you can eliminate the ATF and actually have Attorney generals who focus on eliminating crime, less paperwork, and the Canton police dept. who no longer has to worry about individuals who observe and follow the laws.
