QM has no “reality fluid”. The whole point of calling it “reality fluid” is to remind yourself that it’s standing in for some assumptions about measure theory which are fuzzy and unproven.
My own (equally fuzzy and unproven) notion about measure theory is that anything which has nonzero amplitude, exists. Yes, you can then ask why probabilistic predictions seem to work, while my measure theory would seem to suggest that everything should be 50⁄50 (“maybe it happens, maybe it doesn’t; that’s 50/50”). But I believe that there is some form of entropy in the wave function, and that probable outcomes are high-entropy outcomes. No, I obviously don’t have the math on this worked out; but neither do you on the “reality fluid”.
I could easily be wrong. So could you. Probably, we both are. Measure theory is not a solved problem.

QM may not have ‘reality fluid’, but the thing we’re tongue-in-cheek calling ‘reality fluid’ is conserved under QM!
