Here's someone else's opinion on the matter.
I've just been looking at the MN thread, and in any 'MLM' racket, it's the reason why the victims hand over their money, which is important.
No matter what 'MLM' propagandists might keep repeating about 'distributors buying and selling products', 'MLM' victims really make unlawful losing-investment payments, because these transactions are based on the false-expectation of future reward. The wampum is only there to launder these unlawful losing-investment payments and make these transactions appear to have been 'lawful purchases' based on value and demand. Absolutely anything can be used as wampum in an MLM racket. The more banal the 'MLM' wampum appears: the more unthinkable the truth becomes.
