You need a meta-machine (programmer, manufacturer, power, etc.) for that.
Machines can indeed control themselves. You do it every day

Basically, your problem with the materialistic PoV is that you don't see how it can account for choices. Well, I don't see how you've explained "choices" in an Idealistic framework either.
There is, of course, my preferred explanation of "choice" from the materialistic PoV, and that is Daniel Dennett's from
Consciousness Explained (this will be rather long, but I hope you endeavor to read it all before responding).
Basically (and I really mean "basically" since I couldn't possibly sum up
the whole chapter in one post): An Idealist thinks of a "central id" or a "singular self" that controls the brain's functions. This is not allowable in the materialistic framework, and so we must completely eliminate the "center" altogether. In order to do this, Dennett proposes that all of the different parts of your brain can serve the multi-purpose of "asking" and "answering".
Now, there is an illustration that helps to explain what this means, and that is of the party game wherein one guest tries to figure out the content of a dream that the host (or anyone else really) has had. So, in order to figure this out, he asks each guest yes/no questions and tries to deduce the dream from their answers. However, there is a twist: the guests have not really been told a dream, but have been instructed to respond with a "yes" or a "no"
depending on the last letter of the question that is asked.
So, if he were to ask you "Is the dream about the host's father", you would answer "no", because the last letter of the question ended in a letter that is in the second half of the alphabet. In this game, there is also the "non-contradiction" override rule, which doesn't allow you to contradict a previous answer, no matter what the last letter of the question was. So, if he later asked you "Is the dream about his dad?", you would still answer "no", even though the last letter is in the first half of the alphabet.
Do you understand the game? (If not, I can attempt to clarify any points you don't get.)
Dennett proposes that this is a very close model of what happens in our brains, all of the time (except, of course, for the fact that there is no central "questioner" but rather, all of the "answerers" also serve as "questioners").
Now, to apply it: Let's say that someone insults you. They thus trigger a response from the brain. The different parts of your brain involved (such as the language-producing parts, the parts that deal with emotion (since, obviously, this insult would affect how you "feel"), the "memory bank" (which is full of previous occurances that resemble this one), etc...) begin the question/answer process. This serves as a refinement of not only what you are going to say in response, but also if you are going to say anything at all.
Interestingly enough, this process doesn't necessarily stop after you respond with a witty come-back, since (as you've probably experience before) we often think about what "I should have said" (and sometimes, our memory is remodeled to think that we actually
did say some of the things that we "wish we said").
I'm sorry for the length of this explanation, but it's not a matter easily addressed (and I've only given an
outline).
The Cartesian Split has some logical drawbacks which you still seem to ignore. Hard luck, buddy.
It seems rather obsurd that you would direct a comment about the Cartesian division at Zero, when it is
you who subscribes to a "mind" that exists separate from the "brain" (the main concept behind Cartesian dualism).
