It doesn't matter if there is only one or a hundred. It goes back to a money making revenue for the state.
How much money would the state lose if they did away with licensing and went to Constitutional Carry?
You're pretty myopic - there's several other reasons for an LTC, which is why I'd never let mine lapse and fight any effort to do away with it - chief among them bypassing the NICS checks during purchase, plus carry reciprocity while traveling. I'd happily welcome CC - but leave LTC in place. And at $40 per license, the state ain't got much of a honey hole....
