Nice piece on Mr. Karamazan. This is kind of a trivial point, because it's weirdly obvious, but it's also right: They exist because they provide value. If they didn't, they wouldn't exist. I say this as a middleman.
With respect, there is nothing obvious or trivial about your assertion. There is no shortage of examples of economic agents that provide no economic value whatever (or represent negative value-added, in fact).
With respect, can you give me 3 examples of agents that provide no (or negative) economic value?
