So I'm new to Anarcho-Communism, but really like the general ideas of the system. I have a few hang-ups about the system though, which I'm sure have valid answers that I simply haven't heard yet. So I understand anarcho-communism is a voluntary system in terms of product, where everyone is free to work in field that they choose, so I have a few questions. First, who does the undesirable work that nobody wants to do? Also, what stops the more greedy people from simply hoarding all of the products produced by the system? Lastly, what stops people from committing atrocities (such as harming the environment out of ignorance or laziness, killing out of hate, etc.) in an anarcho-communist state? Thanks for the help guys!
