I like your point.
This is about the only thing in the bible that ever left me scratching my head- “What was this Tree of Knowledge?” and “Why did God stick it in the middle of their garden if he didnt want them to eat it?”
and most of all - What happend to this tree?
The flood destroyed it, maybe?
And if we ate more of that tree, would it have any effect? Would we be wiser? Or would it result in an even bigger disaster?
