I think I see your point, which is that sometimes safeties/regulations are necessary to prevent harm from people that don't know what they're doing. However, I'd counter your firearm example with one of the world's most popular firearms, the Glock handgun, which only has safety mechanisms that help ensure that the firing pin strikes the primer from an intentional trigger pull. You can still not know what you're doing ("what does the trigger do?") and have an ND (negligent discharge).
