No, I understood what you meant. Otherwise I wouldn't have taken a shot at complying. Really RQM deserves its own post carefully dissecting it, but I may not have time to write it.

A very quick but sufficient refutation is that the same math taken as a description of an objectively existing causal process gives us MWI, hence there is no reason to complicate our epistemology beyond this to try to represent RQM, even if RQM could somehow be made coherent within a more complicated ontology that ascribed primitive descriptiveness to ideas like 'true relative to'. MWI works, and RQM doesn't add anything over MWI (not even Born probabilities).
