All individual human thinkings and abilities are one's own life development based.
What ever you are giving us is another personal version.
Quran is a literal book for all, and not just for intellectuals. It says so about itself.
22:16 And thus We have revealed the Qur'an in simple and plain verses. Allah Guides him who seeks Guidance.
54:17 And indeed, We have made the Qur’an easy to understand. Then, is there any who will learn?
55:2 He it is Who has made known and taught the Qur'an.
Every one doesn't need to be a Phd or a professor to understand the guide. Other wise the whole purpsoe of the human guidance concept will finish. A lay man's Understanding will go into the hands of Shaikhs, Mullahs and continuously changing thoughts.
To simplify, why not stop efforts to find different underlay meaning, codes like 19, and personal experiments.
Ever wonder, why we have million sects. This is one of major reason. Every one trying to become a new discoverer.
