Seems a fair question. In a private banking context, it would potentially eliminate the need to pay escrow fees to a third party, without resorting to massively inefficient public ledgers. In the context of e.g. stock trading, it might mean that a traditional bank can connect buyers and sellers over a peer to peer connection and guarantee that their trades execute in order without even needing a centralized book. That's maybe a slightly extreme take, and probably a ways off. But I think anonymity is the least important of what becomes available if you can trust client-side processing.
