This is the real benefit I've encountered. Any time I try to "simplify" financial recording for someone else and avoid double-entry, I inevitably end up wanting to perform a query that would be easy in a double-entry system but is not in any other system.

Right. I didn't mention that a chart of accounts can look different in different companies/sectors. Some accounts may be considered nested (software may even show them as nested.) Then you can roll the totals for all accounts of a type into a general category account like "Assets" or "Expenses." That makes it easier to answer questions like, "how much have we spent in total?"
