I'm not disputing that the brain can make all sorts of observations about what is occuring in the world, merely that if we look beneath the level of the functioning whole organism, then no one is actually doing it.
Here could be the point where you might be obviating 'anyone doing it' too quickly in my opinion:
1) If we go "beneath the level of the functioning whole organism" we are also getting rid of the whole problem altogether in one single sweep, which makes the whole saying that "no one is actually..." into a mere tautology. I'm not sure why you think this is a satisfying explanation?
2) When we say that the
organism does (anything), it sets the description level for where agency and action is perceived to happen, thus it is the 'functioning whole' which is denoted to, and what we certainly don't want to get rid of, obviously.
There could also be some further problems when, on the one hand, getting rid of the agent altogether, and on the other hand, simply referring to a process like 'thinking' as the sole contributor to 'doer'. Mainly, it misses the intermediate stage altogether. Or, it simply replaces a potential explanation with a broad abstraction.
Here is what Dennet has to say about homunculi as explanatory agents:
Daniel Dennett said:
[FONT=Verdana, sans-serif]As long as your [/FONT][FONT=Verdana-Italic, cursive]homunculi [/FONT][FONT=Verdana, sans-serif]are more stupid and ignorant than the intelligent agent they compose, the nesting of homunculi within homunculi can be finite, bottoming out, eventually, with agents so unimpressive that they can be replaced by machines (Dennett, 2000: [/FONT][FONT=Verdana, sans-serif]Are we explaining consciousness yet?; [/FONT][FONT=Verdana, sans-serif]originally in Dennett, 1978: [/FONT][FONT=Verdana, sans-serif]Brainstorms[/FONT][FONT=Verdana, sans-serif]). [/FONT]

Empirically there seems to be quite a bit of evidence for these semi-intelligent (or stupid) semi-autonomous modules in the brain which could directly be involved in creating the first-person 'sense of a doer' (which are empirically detailed rather than abstracted away). Or to use Baars' own words: "[/FONT][FONT=Verdana, sans-serif]
Contrary to some, this sense of self is conceptually coherent and well-supported by hard evidence." (Baars 1996). [/FONT]

Hence, in stead of defining 'away' the doer, it is also possible to simply 'redefine' what the doer stands for empirically. Thus we could propose "many selves" or as Damasio would put it, "proto-selves". We could also propose other selves for which there seems to be some empirical evidence for, like [/FONT][FONT=Verdana, sans-serif]

(in Baars 1996: Journal of Consciousness Studies, No. 3). [/FONT]

Grounding the process in empirical denotations could be a more satisfying approach for describing what is happening, rather than simply sweeping the whole problem under the rug and label it "thinking". It still doesn't mean that there is a central all-encompassing doer (except the whole organism of course); it also doesn't mean each self-center is somehow conscious of itself; and it certainly doesn't infer dualism. It could simply be a better explanation in terms of empirical and functional detail? [/FONT]
