Not sure why this was flagged. It seems a pretty well-thought out, non-troll argument even if you don't agree. Personally I think that bitcoin-style blockchains are pretty useless outside of some very specific cases. Consensus between parties that don't trust each other is pretty much what our entire system of banks, governments, and lawyers (when things go wrong) was created to deal with. Replacing all that with an simplistic algorithm is the worse case of Engineers Disease. I know that a some people have made a lot of money from bitcoin - good luck to them. And bitcoin does have some value if you want to move value around without those pesky government controls. But I don't see how the whole system will not just fade away once the smart people have extracted all the money from the suckers. But I don't have any bitcoin, feel free to ascribe this comment to sour grapes.
