Actually, there are common uses of left hand (counterclockwise = screwing on) threads. Usually, when they’re holding on something that’s rotating.
For instance, if you have real wire wheels on your car that screw onto a single center hub, the big screw cap that holds the wheel on will be reverse threaded. That way the rotation of the wheel tends to tighten rather than loosen the nut.
If you take apart a common home tabletop fan to clean it, you’ll usually discover that the nut in the center of the fan holding it on is reverse-threaded. Again, to prevent the rotation of the fan from “unscrewing” the nut.
So clearly, there’s no reason a reverse-thread can’t work just as well. I think it’s simply a matter of more people being right-handed and it being easier to exert more force to screw on a right-threaded nut with your right hand (and vice-versa for left-threaded. If most people were left-handed I bet “reverse” threading would be the standard).
