It's not so much that it is fallen - you can have a meaningful discussion about whether there was ever a point in history where life was better, or a theological discussion about the nature of any fall from grace.
It's the religious implication in the article that invalidates it. Christian belief is that humanity's fall from grace can only be redeemed through the intercession of christ, and the author links the impossibility of any utopian state with that fall from grace, so obviously the only way to resolve it is theological.
The author's implied statement that any attempt to create a utopia must either come from god, or be religious in nature, is the problem. If, like me, you don't believe in god, and believe organised religions are inherently bad, then at that point the author's credibility is destroyed and the article is just another religious rant.
