I agree that ignoring human nature is a bad move. In fact, a recipe for disaster for many reasons. Repress or disrespect it, and it will come back roaring with a vengeance.
I also agree that empirically, communism is always a disaster.
But I would also say that communism doesn't even look good on paper. It looks terrifying! To naive and frankly clueless young minds with no appreciation of human nature, human society, and so on, a superficial acquaintance with the subject matter might seem nice, as it might play on tropes and juvenile grievances, envies, and sentiments. But an honest look at it by an intellectually properly formed and informed mind will inspire horror. It is a dehumanizing ideology.
Now, that doesn't mean our hyperindividualist, capitalistic, and liberal consumerist societies don't have their share of poison. They do, and again, to a good degree because they misconstrue human nature. But communism or even socialism are no solution to these ills.
(JPII's "Centesimus Annus"[0], among more academic works by him and others, addresses some of this. People often pay attention to his anti-socialist, anti-communist legacy, but remain unaware of his critical stance toward capitalism and liberalism.)
