Nice theory... The only thing I was able to come up with is that the supposed good LORD god said: you cannot have knowledge or I will punish you, but there, I put it right in your view so I dare you! And then the serpent is supposedly the bad guy for encouraging man to learn... Right.. That did seem to me like turning the whole thing on its head. And since it's right at the beginning of the whole bible book that pretty much set the trend for all that followed: massive violence through the old testament and then some weird sort of reversal to love in the new testament...
Sounds a bit like politics: do as I say, not as I do...
