Anarchist Communism has no real life example to even look at and remains entirely as a school of thought philosophical dream because it's a paradox of definitions. It's simply impossible to be with and without structure.

You can have limited rules and have individualistic agency and issues that arise with it, or defined rules with specific limitations that define the agency while still giving social agency but it does not equate to them being synonymous.

Also the party that pushed for this state system dissolved after only 12 years due to infighting on the nature of how it would work. The answer being that the ideologies don't work in practice.
