They had to leave the garden, yes, that was the punishment, what's the problem here?
Adam and his wife broke one of the rules, they had to be ejected from the Garden. I see it like this: The two of them were given Time as a form of forgivness and during this Time they will be able to earn back the garden.
That's not forgiving. That's like if you broke one of your classroom rules, your teacher tells you to get out. Then when you apologize, she says
"OK. I'll give you 5 hours. If you do everything I tell you to do in that time, I'll forgive you and let you in."
What you are saying means that God hasn't forgiven us yet, but we have to earn his forgiveness.
Adam didn't start out on earth (according to what you are saying), he started out in heaven. So if God forgave him, then shouldn't he, and his children (us) be in heaven also? why the hell are we on earth?
So if God hasn't forgiven us yet, that takes us back to the Christian idea of Original Sin. That means you agree with the narrator of the story, and thus you should be a christian.

But, the story changes completely if we realize that maybe paradise isn't in the clouds somewhere, but right here on earth.
Adam was born here, just like us. He reached this higher state of BLISS by following the straigh path, just like we can do. But he couldn't control his desires and ended up leaving that state of bliss.
The original sin is following our desires.
