You sound like Hillary Clinton. The voluntary sharing of early Christians is a far cry from state enforced socialism imposed at the point of bayonets, secret police, and guns. That is why a quote from Mao seemed so discordant I didn't know what to say, except mishmash. Next you will be calling families socialist, except you may know that they regard families as reactionary.
My apologies, I thought the quote from Mao was self-evident in it's meaning; under totalitarian socialism, inconvenient truisms (such as human nature) can be conveniently ignored since they would tend to make the idea of socialism a farce (one thing a socialist cannot stand is to be mocked).
Conversely, it has another meaning: since I own the guns (Mao is saying), history, etc, is what I say it is. If I declare that human nature does not exist, then those that persist in this idea are reminded that I (Mao) have a monopoly of force.
