Back into Eden

An interesting post by Ian Ayres probing how God treats Free Will. It then side-steps into an analysis of God's punishment of Eve, and how it seems rather obsolete via modern advances:

Indeed, the trifecta reappearance in our world of painless childbirth, the appearance of different sex unions where the man does not rule over the woman (pace MacKinnon) and the appearance of women whose desire is not for their husband might all be signs that the punishment is no longer in effect. You see, sin without free will is not even possible. Pharaoh’s failure to let the Israelites go when his heart was hardened by God cannot in good conscience be considered sinful. The reappearance of choice – of women that choose whether or not to desire husbands – opens up the possibility for sin, but it does not indicate that same-sex desire is sinful. Indeed, it may be a sign that we are step closer to the garden, a step closer to grace.

I'm curious how else one can define it (time to call in a favor on Pseudo-Polymath). Perhaps it is humans blatantly flaunting God's will--but then, the Bible is rather clear about what happens when we do that. So--what? Have we finally achieved penance for original sin? And what does that entail for modern Christian theology?
