It's flawed from conception.
Let's say I start a commune and use faith as my only whip, and get people to share through their own free will.
It's still based on the idea of punishing producers and rewarding need; punish those who produce, and reward those who don't.
It's a downward spiral that ends in predictable ways. Either it collapses and disintegrates, or those in charge put a whip on the communes back; justifying the use of force for the greater good.
So it really only has two purposes, to destroy a society, or put a whip on societies back.
