Heaven or Hell? City communes growing and recycling together

Is this the future? While this all looks a bit granola hippy to me (when did I become such a curmudgeon?!) this Swedish apartment block has turned into a more sustainable and happy community, just by making a few simple changes. Not all the apartments participate and I can only imagine how nit-picking the meetings are, but they all seem very happy about it.

Do you think it could happen here? Or would there be too many by-laws and regulations prohibiting it? And are we really going to share our tools?
