i have also heard of this and it is crazy how that works and we dont evan realize it
but i think are population numbers are just to large to get rid of the monetary system without causing violence
and to say crime would vanish that is possible because then there will be no structure to create guidelines
so basically we would turn into a society similar to the omish without the strict guidelines
i just think its impossible to stop the sorce of all evil because without evil then how can there be any good
look at it this way humans are animals but we created are own eco system
so we basically we create are own form of nature and if you observe nature every thing is balanced because some species will naturally go extinct while others will evolve to componsate
so what i am saying is without lions you can have no gazels
