Thomas H. Greco, in this article on the realitysandwich site, discusses the transformation of our conception of money from the current centrally controlled monopoly-and-empire-building kind to a new view of locally created multitudes of exchange mediators.
Contains a section reflecting on the relative success or lack of it of various LETS type initiatives.
"My own inclination is toward "freedom approaches," with a particular focus on what can be done by associations of businesses, by grassroots organizations, and even by municipal and provincial governments. I do not wish to shift control of the money monopoly from one group to another; I seek ways to transcend it." (from the article)
one of the first bits of wisdom i got from michael linton when i first started learning about community currencies comes from And Then There Were None by Eric Frank Russell "freedom i will, freedom i won't" which sums up LETS and open money.
the book is quite entertaining with many other such anarchist homilies.
