In open source production, filesharing, or knowledge exchange communities, I freely contribute, what I can, what I want, without obligation; on the recipient side, one simply takes what one needs. // for the very reason that P2P operates in a sphere of abundance, where a tragedy of the commons, an abuse of common property, cannot occur, or at least, not in the classical sense. In the concept of Tragedy of the Commons , communal holdings are depleted and abused, because they belong to no one and also because physical goods are limited 'rival' goods, they can be taken away. The conflict is between the collective interest for preserving the Commons, and the individual incentive to abuse it for one's own personal benefit. We should note how this theory is based on a 'unregulated' Commons, leaving it without defense against individual predation, and it is therefore misleading as a general theory of the Commons.
