I don't find your arguments at all convincing.  In fact I don't think you've 
even given an argument - just assertions.  

But in a rather trivial sense I agree with you.  To explain Y in terms of X you 
have to include Y.  So to explain subjective experiences, the explanation is 
bound to "include" them in the sense of saying, "...and that's the subjective 
experience." But the explanatory part, "...", can be entirely in terms of 
neuronal processes or natural selection and evolution or culture.  There is no 
need for explanations to be all at one level.  In fact, such explanations are 
often less useful than those that cross levels.  To explain aesthetic 
preferences in terms of subjective sexual feeling toward parents, as Freud did, 
isn't very useful (even if it were true).  How much more interesting to explain 
them in terms of dopamine and serotonin (if possible) or natural selection.
