We're heading towards a cashless society. With the dominion of Visa and Mastercard showing no sign of shrinking, it’s becoming increasingly necessary to scrutinise what this shift towards virtual money really means. Brett Scott is an author and former banker who is deeply committed to evaluating the dangers of removing cash as a payment system. He sat down with Aaron to talk about Bitcoin, gold and the central paradox at the heart of modern libertarianism. His new book, Cloudmoney: Why the War on Cash Endangers Our Freedom, is available from Penguin. * Novara Media's supporters keep us entirely free to access.
