You seem to be using the term "workplace democracy" to erase any control that he public might assert of the overall management of land.
Yet, the land itself demands to be controlled by no particular faction among the public, but rather by the public as a whole.
The interest of everyone is not only in controlling the enterprise in which oneself is a participant, but also the broader practices over how land is managed and enterprise is interrelated.
If an enterprise seeks use of lands and buildings, then the public has an interest in regulating the particular access to them by the enterprise.
