Arbitrary means that the choices were random choice or personal whim as opposed to any reason or system.
Just having different systems, or choices, does not mean it is arbitrary.
If your list includes, good food scene, but mine doesn't, that doesn't mean that I could call that arbitrary. Good Food is obviously a part of quality of life.
NOw, if you included, "lots of brightly colored flowers", then we are talking pretty arbitrary.
YOur refusal to explain why you consider the list "Arbitrary" I guess is sort of your way of admitting that your issue with it, is that you don't want to admit that California, has a shitty quality of life?
