The basic idea of regular anarcho-collectivism, mostly expounded by Bakunin, is that the economy of a commune should be democratically centrally-planned at a meeting, but with the taking of jobs being optional, doing one-hour of any job giving you one labor-token — with more difficult or dangerous jobs being democratically assigned more tokens, and everyone being provided with a baseline amount of tokens.

Now this is all, of course, a bad idea. Not as bad of an idea as anarcho-communism, but still.

Democracy is extremely bad at satisfying any sort of minority needs, and is generally terrible at figuring out how badly anyone needs something — it reduces that down to the binary of whether or not they care enough to vote for it. Further, planning everything in periodic meetings, for an economy of sufficient size, becomes an impossibility. There are far too many details happening far too fast — amongst them not only which jobs need to be done, but how they need to be done, and how much pay they deserve.

Market anarcho-collectivism is an attempt to take this and fix it — stripping out all the democracy and central planning, but keeping the collective ownership of means of production and the worker self-management — i.e., retaining the socialism.
