One common definition of money is: a symbolic representation of value. There is a hidden assumption contained in this idea; namely, that value is something objective. It's not. Clearly, we don't all value the same things. Most people do not value things like crack-dealing and human trafficking. But some do, obviously, or there wouldn't be so much money to be made from those things. One of the many destructive effects of using money is to render extreme value conflicts invisible.
Let's say I'm a seller of shoes. A customer enters my store and offers me money in exchange for my wares. I have no way of knowing how he acquired that money. For all I know, he may have kidnapped and sold a child for it. Let's say he did. In taking his money, I am essentially, although unwittingly, affirming that his act had value, and directly rewarding him for it.
The idea that value can be objectively represented is socially destructive and insane. It's also very convenient for psychopathic criminals, if the rest of us believe it can be.
