Reciprocity isn't all that, as pointed out. And the comparison to a driver's license doesn't look so good, although the author may have meant well.
CCW may be considered a 2A right, but auto licenses are very much considered privileges. We lost our battle from day one when motorists were required to walk in front of their vehicles swinging a lantern to warn others they were on the road.
In other words, the Fudds were in control and had no idea how much of their own rights they were giving away - as usual. We now have a requirement in every state that you must pass their test and possess a Driver's License on you anytime you are behind the wheel - along with insurance and a motor vehicle that has passes a state safety inspection. Including in many cases testing to determine it still has operating emissions controls.
Translated in a worst case scenario, you'd have to possess your carry license - which is ALREADY more expensive in many cases than a driver's license, have gunfighter insurance, have your weapon inspected to make sure it conformed to safety standards and was routinely maintained. About the only positive glitch would be the requirement it have a suppressor to prevent damaging the hearing of bystanders and the perp you had to shoot.
Which greatly restricts its concealability, eh?
The author was possibly trying to tweak the anti gunners, sure, but their response if forced to accept things is to always insist on a poison pill, and it the process of legislation, well, it's like sausage, you sometimes don't know what gets included. And that IS very much a part of our somewhat progressive journey to expanded gun use.
So, the concept comes across as just another opportunity for some otherwise gun friendly legislators to prove once again how subtly they could stab us in the back to get whatever concessions they needed down the road. If we elected statemen instead of lawyers and used car salesmen it wouldn't be so bad - but like the Fudds who insisted that those newfangled horseless carriage operators needed to prevent their animals from going wild, we'd be dirtbagged by the public who trades away their rights for a little security.
