Blockchains are unique because they 1) allow thousands of governance systems and monetary policies to be tried at the speed of software with 2) in some cases, much lower consequences of failure. As a result, there will be a Cambrian explosion of economic and governance designs where many approaches will be tried in parallel at hyperspeed. To be clear, I am including economic design and monetary policy (said another way, incentive structure) in governance because, like other aspects of the system, they can be modified as time passes.
