I agree with your premise. To my mind, the central conflict in Dark Sun is that magic is bad, and its continued use by the sorcerer-kings is actively destroying the world. Not having an alternate source of supernatural power makes concepts like the Veiled Alliance and preservers in general more compelling.
It also helps to center the dichotomy between arcane magic (dangerous, but compelling if controlled) and divine magic (service to the land itself).
