It can be had by simply taking from the shelves and not paying at the register.
As long as the workers produce the goods we don't have to use money to account for the labor.
We do need an objective measure to insure that we produce more than we consume in order to not parasite on the work of others.
I have suggested hours of labor, though a better measure is sure to exist.
I have no clue who is preaching the message today, I haven't heard it from anybody, and found it in the writings of Goldman, Berkman, and Spooner.
