The title of the post got me, and Derman's story kept me reading to the end. Great post!

Besides being a medium of exchange (which paper money is), money is supposed to be a tool which offers us options. The options we have with paper money are limited, but we're just discovering how cryptocurrencies can give us options we wouldn't have imagined ten years ago.

If we can get more freedom from something we have and use, we should have more of it. Cryptocurrencies help us gain more freedom, and they help us re-imagine freedom in ways which favor us. It's only the beginning with cryptocurreny!
