I don’t see a flaw. If we can grant the possibility of an arrangement of matter that somehow mirrors human consciousness as it exists in our current universe in rocks, then I think it’s fair that given infinite variations that some of these universes will contain rocks with the exact same form of consciousness as Evelyn’s. It’s absurd but is logically consistent with MWI. If we don’t grant that possibility- I would simply ask .. why not? It’s not like modern science has a firm enough grasp on human consciousness to rule it out.

I think what you write about themes of depression and suicide is well written and an important part of the film. I suppose I have just generally left those themes as an unspoken assumption when I mention themes of absurdism, as the question of suicide is a core tenet of Camus absurdism.
