So to combat the cycle of diamond inflation and devaluing, Cubfan has created a system that can produce a finite and controlled number of books (which can't be duplicated due to copying mechanics) that he proposes could be used as (for example) Hermit Cash, consistently standing in as currency and being able to be turned in for diamonds. Since there's a consistent amount of Hermit Cash, its value relative to diamonds would only ever increase.
He's re-inventing paper currency on the diamond standard. And has made himself the mint. And the bank.
This really is the Season of Infrastructure and Bureaucracy.
