You are right that true nothingness (TN) is not actualized. You are also right that the actualization of ALL (TE) is nothing like reality. Where you are wrong is in ascribing lack of meaning to these concepts.
You no doubt agree that "stuff" is actualized in reality. Therefore, how can you claim that it is a meaningless question to ask, "instead of "stuff", why isn't there no "stuff"?" From this proper question and angle, the actualization of TN is anything but a meaningless question.
Now, as TN is not a meaningless concept, than neither is TE. And as TE fits in a dichotomy with TN, then existence can be explained as either TN or TE as neither requires a cause. This is inescapable logic.
Now, the true fact that TE does not describe our reality does not make TE false because the logic is inescapable. Instead, one must assume TE is true. However, in order for TE to describe our reality, one must place a Constraint on TE. Therefore, TE with a Constraint does describe our reality, and the truth of the Constraint can be easily justified as a necessary logically possible actualization of TE.
The problem with your assertion that you can simply say God exists and creates everything else is that your theory cannot explain why TN was not actualized. TN does not contain a God. Therefore, no God could stop TN from being actualized. Only a dichotomy between TN and TE can explain why TN was not actualized.
