The only way you can enforce a resource based economy is through totalitarianism (at a degree that is probably impossible). Otherwise, people will acquire wealth, and a money will emerge spontaneously.
May I disagree.. If anyone have plenty of anything they want.. greed should disapear by default. The earth have enought to satisfy everyone. The scarcity is a consequence of the actual monetary system, wich enforce this scarcity. For the first time in human history, we have the knowledge and the technology to overcome any sort of scarcity. History cant apply as we've never been so aware and technologicaly able.
We are seeing the begining of a new era, and the past milleniums of "trade" begins to show as possibly obsolete for the next society models..
The trade concept is prehistoric, when we will learn to do better, we may became a civilisation. It's in our value that the shift must materialize.
No, sorry. You are dead wrong about this. Scarcity in economics is a consequence of the inability of a given atom to be in more than one place at a given time. It has nothing to do with money. I can't imagine where you got the idea that money is somehow causing scarcity.
It may, someday, be possible for many things to be too cheap for anyone to care much about, but they will still be scarce in the economic sense. Also there is no reason at all to think that
everything will fall into this category, and there are instead very many reasons to think that many things will never be in this category.
