As to summarize the main arguments for this rejection I will try to summarize this as follows:

*Anarcho-communists reject workers direct appropiation of the products of labour since they see that labour on itself (whether collective or individual) cannot be seen as the origin of the existence of consumption goods since one should also take into account the knowledge and the tools used for such production as well as the social context and the natural environment from which the original transformed item was extracted from (this latter point could be seen also as a green or ecologist rejection of LTV). As such, anarcho-communism sees that production should be accountable and determined by the local community in which it exists. This could be seen motivated variously by reasons such as the lack of awareness of the social impacts of private property production without communitarian or collective control such as lack of consumer control and protections involved and so it can also be argued lack of motivation on production (whether in private capitalist or collectivist worker controlled) on takin into account environmental and social impacts. This is a main point which has to do with the "commune" part in the word "anarcho-communism" and so it is the reason why Kropotkin himself as well as later anarcho-communists had important reservations with workerist anarcho-syndicalism. Kropotkin said "No distinction can be drawn between the work of each man. Measuring the work by its results leads us to absurdity; dividing and measuring them by hours spent on the work also leads us to absurdity. One thing remains: put the needs above the works, and first of all recognize the right to live, and later on, to the comforts of life, for all those who take their share in production.." In this sense anarcho-communist tends to focus more on the real need and the importance that this has for an individual or a collective than either market exchange value or amount of hours given by workers.

Do you appreciate the concept of communal property vs non-communal property? If you do, then people outside the commune could have private property, and communal-anarchist or libsoc societies could live along other (or dare I say within polylegal/ polyorganized) anarchist societies. If you don't, then does it make war/tensions innevitable? — must you purge private property from outsiders?

(yes, well, I *am* tooting my own horn…)
