No.. The are others.

For example, the "United Order" by Church of Jesus Christ of Latter-Day Saints, which they experimented with long ago, but no longer implement.

The United Order is all voluntary, unlike a forced-collectivist "democracy". You can leave any time you want. You voluntarily donate your excess, and not everything like communism. You own private property, unlike communism. You are free to do what toy with your private property.

It boils down to individual free agency vs. forced-collectivism.
