Well, unlike most currencies or commodities bitcoin can be traded at volume for currencies outside of a monitored environment. This means using bitcoins in a trisection does not effect the trading price, and people could trade in 'dark pools' or face to face for amounts significantly above or below the current 'market value' while having no effect on the market price at all. Even if it where tracked people buying things with bitcoin can just as easily drive the prices up as down. As with all transactions you must take into account the value of both sides of the transaction.
