Instead of how communists usualy go about this, and want to progress from first gaining the political power of the state, turn it’s capitalist mode of production into a socialist mode of production, under the dictatorship of the proletariat, and then (what should have been done) gradually turn the state into a socialist democracy and later on fade out the state when a classless society is being reached.

The socialist states (which were never communist by the way) however have almost all disapeared.
ZeitGeist is unlike any of the existing systems (capitalism, fascisme, socialism, communism) since the ZeitGeist movement wants to take a big leap into a society without trade, and therefore without a money system. At least that is what is being proclaimed.

Instead the society is resource based. I would guess that instead of the current faulty money system (in which money exists as debt, and can be created out of thin air), the ZeitGeist movement in fact re-establises a more durable money system which is based on the available resources. This would seem like a good step, since it is obviously a mistake to have a money system in which more money can be created then can ever be sustainably be delivered at the basis of using scarce resources.

To me this then means that the role of money in such a society will be transformed and will be directly connected to crude materials, but is not done away with. Further the decission making political process is done away with and replaced with logistic computers taking that role. Supposedly also the role of labour would be replaced completely by machineries and robots. That aspect is very futuristic and utopian. Although certain parts of the labour process have indeed been replaced already by robots and machines, to have a whole society, even a small one, operated at the basis of automated machines and robots is quite unimaginable. Machines and robots currently still need designers, maintainers and repair, and only part of the labour process is automated. Even when we could grant the theoretical possibility of having a complete automated form of production, all this would be quite costly and unaffordable, even if only a small community were being serviced.

To do this on a planetary scale for all of humanity is simply a step or two too unimaginable. The poorest 10% of the world population would already be satisfied having clean drinking water, housing, food, education and healthcare.

For a more realistic viewpoint in how to deal with upcoming resources scarcity, we could better look a the “experiment” Cuba has undergone. Due to circumstances in the nineties almost all trade relations with the former easteuropean states were lost, and they had to take drastic steps in reducing the use of almost anything, from oil to pesticides and stuff.

Still, thanks to the power of their community, they managed to survive. Automobiles were replaced by bicycles and buses, tracktors with oxes, pesticides with biological alternatives, and instead of large agricultural farms, many smaller and more labour intensive farms emerged, including urban farming.
They grow more vegetables and have a more healthy diet, so it seems things are not that bad.
