I should add that there's one area where blockchain systems have a pretty strong advantage: establishing a sequence of events. Court cases often come down to who had the better evidence. If you sue me saying you never approved something, but I have meeting minutes showing otherwise, then I am more less going to win by default. Likewise if I say you never had authority to withdraw money from the company account, but you can produce a copy of an authority letter held by the bank with your name on it, you win. Blockchain promises to shortcut a lot of evidentiary stuff, which is a win. That's why there are so many banks interested in distributed ledgers, title registries, supply chain custody and so on.
