Excellent. It seems like many of the Austrian School are stuck on gold as the only "true" currency. While that may be true in the physical world, it will never be able to compete with fiat systems in the digital world. There needs to be an alternative. I hope many of them come to understand that currencies like Bitcoin don't want to replace gold, but to augment it in the digital world.
The people claiming to be Austrians that denounce any currency over another are not Austrians at all, they are people introduced into economics by Ron Paul, who has no interest in discussing Austrian theory of money, only the Austrian theory of government and money...
Gold is a terrific way to control the government spending, as they only have a limited resource...
As for economy as a whole, even paper currency is not "unworkable" so long as there is a competition, the problem with government money is fiat legislation and credit expansion...
