Cash is definitely a claim on a productive asset. It is used to buy food, shelter, and pay taxes. Perhaps you're referring to the USD no longer being redeemable for gold? Ironic considering I cannot eat gold or use it for shelter. Any portfolio manager of stocks and bonds will tell you cash is a powerful asset because of its general state of constant value. Stocks and mortgages are not represented by the blockchain, their legal ownership is represented by titles given to their owners by government institutions. Your response would be more adequate if you disproved the previous comment by actually listing a fundamental of Ethereum instead of claiming vitriol.
