Returning to the Garden of Eden

I’m not religious and I’m not a biblical scholar, but as I understand it, God made Adam and Eve to frolic naked in the Garden of Eden without cares for such things as money.  Stuff happened, and then God kicked them out.

My question is, why don’t believers try to return to such a life?  It seems that the most vocal biblical followers are the ones who would call people who frolic naked in a garden without any concern for money “Dirty hippies who need to get a job!”

I’m sure someone would say that humans on our own can’t return to the innocence of life in the Garden of Eden without the grace of God, or something.  But I’m just asking why, if humans were made to frolic naked in a garden, why is that now usually considered a bad thing?
