After reading your post I definitely have new insight and understanding into the merits of a "personal coin". I'm pretty sure this was the underlying intent of the WAVES platform (well that and making money), and how you refer to "release your own greed", as at least one mechanism to successful implementation - I like it.
As an American with somewhat non-typical Marxist "tendencies", the concept on the surface sounds great - but I wonder if some of the same destructive forces that always dismantle genuine social movements, will once again have the same effects here. Your statement that the individual should do;
"what's best for the network instead of what's best for themselves alone"
