The idea that a character at that sort of power level could survive things that would redmist a normal human is entirely plausible, the issue is D&D's refusal to allow certain characters to scale appropriately. If we accepted that the 150 HP Barbarian was Thor or the Hulk instead of Conan, there'd be no issue with him surviving a dragon bite or a fall from orbit.
