Avocados are, of course, not an ideal benchmark for value. Anyone who regularly buys avocados knows that their prices aren’t very stable. Prices in the US can easily range from $.50 to $2.50 depending on a variety of factors including the type of avocado, season, location and international trading dynamics. Indeed, the price fluctuations of commodities, including gold, make it impossible for any single commodity to back a price-stable currency. The Consumer Price Index (CPI), which the Federal Reserve uses to benchmark the value of US dollar, is calculated by analyzing the US dollar-price of hundreds of goods people tend to consume: milk, gas, prescription drugs, etc. The Fed uses that information to fulfill its two mandates: to maintain a low inflation rate and to encourage full employment through inflationary and other monetary policies. Instead of using the CPI to keep inflation near zero as Hayek would recommend for a private token currency, it tries to keep it around 3% per year. This inflation makes the US dollar a less than ideal benchmark for a price-stable cryptocurrency.
