What's gold really worth? Central banks sure don't want you to find out

Good comprehensive response to criticism by the WSJ's Brett Arends. In sum: any criticism of gold as money tends to fail by virtue of the fact that any flaw of gold applies to paper money but even moreso. The only advantage paper money tends to have is being more widely accepted for "spot" transactions as currency -- but this is weighed out by serving as a poor store of value in the long run (i.e. a money).
