Perhaps an alternative interpretation may be to attempt to identify exactly why seemingly arbitrary units of particular currencies are at all valuable - one interpretation is, quintessentially, most people are interested in money because of the human capital that money affords. What exactly is human capital? Well, the human capital that is responsible for the impressive technological progress in the past few decades, or, the human capital that organizes and maintains the modern infrastructure that allows a vast proportion of many populations around the world to afford a much higher quality of life (one can remind himself/herself of the necessary infrastructure that's required for hot showers and flush toilets). We do not need to grow our own food, or fabricate our own electronic devices, nor perform self-surgery, we exchange our own human capital labor for others.
In fact, BlueMoon is such an illustration of the value of human capital, that a significantly greater amount of excitement is typically introduced when erotic fiction can be constructed dynamically with a compatible partner. However, the human capital value of writing partners on forums such as BlueMoon is not necessarily directly valued in USD terms, and this is considered to be good cultural practice by many. Although one would not be surprised if, moving forward into the future, there emerges a certain type of "professional writer" whose niche is solely to engage in dynamic erotic writing with clients, in the same way that there is such a thing as "phone sex" (audio as opposed to written).
Yet, a point to consider for many is, are the economic systems in the modern world fair in their allocation of units of currencies as a means of supposedly trying to track human capital productivity? Although it is understandable that the doctor or the computer scientist should be highly valued in their human capital contributions, and they are, should stock traders be valued so greatly in certain financial systems? What do stock traders contribute exactly? And why aren't caretakers potentially valued to the same extent? There have been centuries of discussions in the political sciences, and without becoming too political, many suggestions of alternative economic systems have been provided.
