Based on your incorrect assessment of why people get involved and whether the products they sell have zero value. Value is inherently subjective.
And the elements of fraud don’t apply here. There is no false representation upon which these people are detrimentally relying. By and large they are trying the product and liking it. What’s wrong with that? Who are you to say that’s wrong? Essential oils seem bogus to me but people believe they see a benefit . Maybe it’s a placebo but placebo is a real effect that for a given person may really bring them relief from symptoms that is worth paying for, TO THEM.
Again, why do you get to say that is wrong?
