Perfection is not required for one system to be better than another.
Communes don't work. Most never get off the ground. The ones that do rarely make it longer than a decade. And there are basically none that have lasted longer than a century (the only group I am aware of in North America are some sects of Mennonites).
Whereas essentially the entire developed world lives and thrives without the concept of communal property (outside of marriage).
