Is the framing of "bread" as a consequence of the Curse a deliberate anti-civilization polemic in the J source?

While the later Priestly material rehabilitates bread as a holy object (like the Bread of the Presence and manna), the foundational narrative treats the staff of life as a byproduct of the fall. In both Genesis 1 and 2, the human diet is strictly defined by gathering. Humans are given every seed-bearing plant and every fruit-bearing tree. However, arguably the most fundamental element of Ancient Near Eastern life, bread, is entirely absent from the pre-fall world. It only appears in Genesis 3:19 as the climax of the curse where it is linked to the sweat of the face and the return to the dust.

This framing seems interesting compared to other regional myths where bread is a symbol of progress. In the Epic of Gilgamesh, the wild man Enkidu gains his humanity specifically through the consumption of bread and ale. For the Mesopotamians, bread was the technology of civilization that separated humans from animals. In the J source, this dynamic is inverted. The labour required to transform grain into bread is portrayed as a perpetual reminder of a broken relationship with the ground.

I'm interested to know if this could be interpreted as a deliberate anti-urban or pastoralist polemic against the grain-based bureaucracies of the surrounding empires at the time it was written.
