I think a large part of nowadays' use case of blockchain-based technology is to skirt regulations and conduct transactions that would have been illegal/attracted scrutiny if done with the traditional, "trusted" channel. Those people have to go with a non-legal channel, where trust becomes a very tricky and important thing. In that context, blockchain becomes a really good solution. i.e. it's not that traditional banking is not trustworthy. It's just that many people want to avoid legal channels. That's when blockchain comes into play. The increased regulation efforts by multiple governments might change the landscape, or not. We'll have to see.
