That's the entire point when the goal is to achieve a public, immutable, decentralized ledger that prevents double-payments without needing to trust a third-party to adjudicate properly. It being inconvenient makes it exceptionally difficult to edit history.
Whether that's a useful goal is less clear when nearly all of modern society relies on trusting parties at some point along the way (will the thing you bought be delivered to you? Will the service you purchased actually be rendered? etc).

A financial process being unwieldy hasn't really been an issue historically. Why are most publicly issued stocks in the US owned by Cede and Company for example? No one that has stocks really thinks about the underlying system (the fact that they have contractual rights to stocks rather than actually owning stocks), as long as it ultimately works.
Where things have broken down in my opinion is how centralized the systems have become with massive exchanges being the only realistic way to interact with them. In the same way that a bicycle wasn't designed to be a moving van, these systems weren't designed to be centralized. With that being the reality though, the entire blockchain backbone is mostly useless, and at that point it really is an inconvenient database.
