Hobbes wrote:It is the concept of "personal possession" that leads to greed.

It is hard to "possess" more than you need for immediate sustenance if you don't have "money" to buy it. It is hard to do anything but sustenance farming / fishing / hunting / gathering, like ore mining etc., without "money" to turn your day's work into food on your table. And you cannot "amass posessions" when those posessions are essentially perishable.

On a sidenote (and before I shut up because I went way off-topic here), check out the concept of "negative interest".

Like I said, money is just a medium of exchange. You don't need it to exchange things (though it makes it a lot easier) and people have been exchanging goods and services long before the invention of money.

We are off-topic, aren't we?
