I don't think I could call this being close-minded. It's just fact against something highly unlikely. Even if we would go to this soul thing, in outer body experiences during clinical deaths, the "soul" still remains close to the body until brain damage is too severe for any function to be possible and be completely dead.

By taking Enel's example, the DF does not leave until the soul leaves making it impossible in simple terms to revive someone without a devil fruit. And that is if you take into consideration the concept of soul, because Brook's case is different as his DF isn't completely explained yet and there are too many uncertainties to use it for anything viable.
