Since the product of their labor does not have an exchange value, but a use value for a community of users, it is characterized by the production and distribution of the product of labor outside the market sphere (a post-capitalist form of the organization of production).

Unless peer production is economically self-sustaining it cannot be characterized as outside the market sphere or as post-capitalist. Unless it is a stand-alone alternative to markets and capitalism it is at best in a symbiotic relationship with them and at worst it is a victim of capitalist exploitation.

In order to prevent symbiosis from becoming exploitation, peer producers must IMO retain some ownership to the products of their labor in the form of conditional property rights, patents, licenses, etc. that entitle them to a portion of any subsequent commercial revenues while simultaneously granting free reproduction rights for non-commercial use.
