Well written, and well said. I would have to agree with most of these points.
I believe Adam would have had more choices than just whether or not to eat of the tree. We see that he named the animals, tended to the garden. But i do see what you mean in that he was more or less provided for in a sense. As in, he could just grab food from anywhere really as it was readily available. He didnt have to forage.
To clarify, by this I meant that was the only really difficult choice, where it had to be made and it was between two direct opposites, with eternal consequences.
