As is often the case, the same word can be applied to different things. The anarchist method of collectivization can be seen in the organization of base communities in Chiapas.

In this model, work-related property is collectivized on a voluntary basis. From there, if there are irreconcilable disagreements, sub-collectives are branched off to carry out their work independently. The overall goal, however, is still to make the world better for everyone involved.

Thus, this kind of federation allows both individualism and community to be preserved. More discussion of collectivization can be found at http://csf.colorado.edu/mail/ipe/2002
