I see that you seem to have misunderstood what I wrote.
The entire Medrash that you quote is found in Pirkei D’Rabi Eliezer Perek Yud Beis (Chapter Twelve) towards the beginning.
It states the following ( I am translating to the best of my abilities)
“And G-d took the man and placed him in Eden L’uvda U’lshamra, To work and to watch it, And what work was there in the Garden that it states To work and to keep?
Perhaps you will say he had to plow the fields or tend the vines or cut?
But we know all the plants sprouted by themselves!
Perhaps you will say that there was work in the Garden of Eden to water the garden?
But was there not a river that went out of Eden, as it says And a river went from Eden?
Only what does it mean To toil in Torah and to watch the Derech Eitz Chaim “The way of the Living Tree” and there is no living tree other than Torah as it says “A living Tree for those that Grasp on to it”.
So you it is not a “commentator”, the very Medrash that you quote continues on to state categorically that it is impossible to mean what you are saying it means.
