seems like the same fundamental misunderstanding as the venus project people have. business to business barter could never take the place of money because it is necessary to have a heterogeneous unit of account inorder to have prices. Prices are necissary inorder to calculate profit and loss and inorder to account for opportunity costs. Calculating profit loss and opportunity costs is necessary in order to rationally allocate scarce resources and to communicate, in a useful way, the decentralized knowledge of individual market actors. Self issued credit is great, but it must be priced, and inorder to do this you need a widely understood unit of account.
so imagine trying to know how many shoes an elevator is worth, and how many elevators a mongoose is worth, and how many mongeese a cheeseburger is worth, with out using "money" as an intermediary step.
We dont need "bater/money/unit of account/price" to operate a global sustainable society.
The point is that "money/unit of account" are creating scarcity. In a scientific point of view, there is no real scarcity, and ressources could be used in an efficient and intelligent way, or being replace by something else if there is not enought.
Without "money", the science and technologies would be allowed, and then everyone could live a much more descent life.
Many technologies are not availlable because they are not profitable. Removing the notion of "bater for profit" then every car would be electric, and much better than actual cars.. Everyone would have access to free and clean energy, and no one would suffer from hunger or cold. Money/batter, or better called "profit notion" is the source of the scarcity.
I think you just dont fully understand what the Venus Project/Zeitgeist movement have come to.
Many technologies are 100x better than actually availlable one, but not availlable because they cant be produced for profit.
Worse, "Money/Batter" forces competition, wich is not as good as cooperation.. Imagine if every Pharma Research Corp stop to keep their info secret, and they all regroup and share knowledge and ressources, Cancer, Aids, Ms and more would be cured ..
Money/Batter is the brake to evolution..
To be able to function without Batter, a majority of human on earth have to evolve their value, and this have to begins to education of our children !
