>Information asymmetry. How do I know who will be a polluter, a murderer, an immoral person, or a criminal in the future. You're creating friction rather than reducing inefficiency. Exactly! You don't know. But you don't know now either. In the future the market will know. And why should the subway shop that the polluter bought a sandwich from be punished after the fact when we find out he is a polluter. Instead, throw the guy in jail and fold the blockchain over him so that the sandwich shop is connected to the original person that unknowingly paid the polluter. You can't know, but you can guess. It isn't even that hard. And while you are trying to guess all the sandwich shops are showing you why they are the most profitable and why they can deliver you the most value. >Also, the current monetary system already has the idea of "decay" built in due to the Fed targeting a 2% rate of inflation every year. Inflation is unpredictable and under less control than now appears. See 1970s. Predetermined decay is a carrying cost. Unexpected inflation is a theft. >Also, not being able to trade "prefs" strikes me as a silly idea; one that you can't enforce and that a black market would form around relatively quickly. This is just a technical issue that building on a blockchain solves. Post transaction data analysis can find collusions.
