I disagree with your assessment that collectivism is not communism. What makes you say that?
The only difference between anarcho-collectivism and communism is that, in communism goods are distributed based on need, and in collectivism goods and workers salaries are determined in democratic organizations based on the amount of time they contributed to production.

"For the recognition of private property has really harmed Individualism... by confusing a man with what he possesses... The true perfection of man lies, not in what man has, but in what man is." - Oscar Wilde
