Thank you for the interesting explanation.
The metaphors in the least abstract uses -- Job/Ecclesiastes -- are possibly (although marginally due to their rarity and late date) interesting for the hypothesis of Yhwh as a "storm-god" (Southern variant of Baal).
Originally, YHWH was only Jews' God.
Since "Baal" is a meaning of a "lord", your explanation is correct possibly.
I think that your explanation is interesting, IMO.
But the Bible is the book of "faith."
I think that it is not a book for merely reading from the academic point of view.
And in the New Testament, the divine name is not used any longer.
I think that it is because the Christians in the first century understood the meaning (symbolic meaning) of "I AM", IMO.
