My favourite euphemism to refer to this general form is "One man's Ponens is another man's Tollens" (https://en.wikipedia.org/wiki/Modus_ponens / https://en.wikipedia.org/wiki/Modus_tollens). The idea being that, in formal logic, if you have a material implication it can go both ways:

Stupid Rule X implies Stupid Rule Y

(Ponens) Stupid Rule X exists, therefore Stupid Rule Y should exist

(Tollens) Stupid Rule Y does not exist, therefore Stupid Rule X should not exist

I was mulling over the 600 hour's requirement to become a licensed hairdresser, and found myself wondering, "is that really that unreasonable, especially compared to carrying a concealed handgun?"

After all, being a hairdresser necessarily involves wielding a variety of sharp objects around someone else's head, several hours a day; there's a lot of potential for injury there, possibly resulting in lasting disfigurement, so that risk requires a lot of mitigation. By contrast, teaching someone how to carry a firearm responsibly is largely a matter of "keep it holstered unless and until a very limited set of circumstances apply in which you're justified in inflicting lethal injury on someone." If all we had to teach hairdressers was "leave your scissors on the cart at all times, unless and until you have reason to need to stab someone with them," hairdresser training could be *a lot* shorter. Concealed carriers don't need to know how to *safely* point a gun at someone's head eight hours a day.
