i am not saying it's not a problem, nor that it's always easy to fix. but it is fixable. banks will keep double records, and solutions will be found for corner cases (in the end, even write-offs). but it's simply a very different mode of failure. a corrupt database will typically fail to work, or? a system may fail due to this. this definitely costs money and nerves of all involved. but yes, the response here is bad.
