I can think of one scenario where being public and 100.0% reliable has meaning. The scenario where accountants and human intervention are the thing you want to be rid of. Financial transactions. Before someone just points out those are just more tokens and that we're all betting on their value, etc., etc., I'm deliberately skipping the meta-argument. The point is that finance systems do exist, already, and adding a trusted distributed transaction ledger does add value.
