I think that's a disingenuous comparison. If you're comparing to banking software, imagine a plumber that causes four floors of a high-rise to get flooded, leading to 5-figures of damage and additional lost time. Or perhaps an underwater plumber, where the cost to fix the leak is high.

If we're looking at house plumbing, it might be more fair to compare it to a CRUD app that facilitates iguana breeding (unsolved problem here, folks!).
