You mean as in "the wavefunction exists"? I meant that as "the universal wavefunction exists", like in asserting the Everett interpretation applied to the universe as a whole. Not sure how you get nihilism from that. And it's not about the other stuff being illusory but about it not being fundamental, just like a classical materialist wouldn't call a car illusory merely because it reduces to more fundamental atoms.
