As the state specifies (since day 1 of CHLs here) the license provides a benefit. Those benefits pertain to purchasing firearms, exceptions to certain laws and defenses to prosecution for certain charges.…So why even have licensing? This is more of a philosophical exercise at this point.
The state also, conveniently, absolves itself, it’s agents, and instructors (among others) from liability of a license holder’s actions. That too has been part of the law from day one.
