Well, it's possible and practical -- though not easy -- to make money as a day trader, so there's obviously value in it beyond the direct relationship to ownership.

I suppose it is a house of cards (or maybe collaborative hallucination is a better phrase), but I think that any system that tries to connect abstract
philosophical ideas to the concrete real world in a usable way is equally flimsy. Look at the concepts of marriage, goverment, or law. Examine those beyond just how they're used and praticed. At some point you cross a boundry between how it works and what it means.
