There is so much fallacy to his argument, not sure where to begin. Try exchanging gold for anything without some usery fee.
There is no fee. You're talking about an arb fee for exchanging between a debt based currency system where the USD is unit of account to a different system. If metals are the unit of account, there is no arb fee and no debt based currency or usury fees either. If you transfer into bitcoin, you're back into a debt based usury system once again. Bitcoin does NOT remove the middleman, only physical commodity based currencies like metals do.
