Its not even digital gold at that point... I can trade a piece of physical gold for free.
But you can't divide it into 10,000,000 pieces. And it's not so easy for someone say in Turkey to get his gold coin to a dude in Vancouver.
There is no purpose in dividing it into 10,000,000 pieces if it costs more to transfer those pieces then they are worth.
Okay... and those points are mutually dependent. It's still hard for you quickly transfer a full gold coin across the ocean.
