All Human Utopias are doomed to fail. Human Utopias are defined as only including the "Good" parts of Human Nature and Excluding the "Bad" parts of Human Nature. However, history has shown you cannot bet against Human Nature retaking its full expression in "Good" AND "Bad". Don't ever bet against Human Nature. You cannot win. Bet ON Human Nature to overcome all attempts to contain or distort it.
Organized religions are Human Utopias for their members. Look under the hood, and wait long enough, and you will find Human Nature is still expressing itself fully in all its dimensions in utopian religions. Loving eyes can be blind.
