they're intuitive to somebody - just not the software engineer. This simply means there's some domain expertise which isn't available to the engineer.

Not necessarily. There are a lot of domains where you're digitizing decades of cobbled together non-computer systems, such as law, administration, or accounting. There's a very good chance that no single human understands those systems either, and that trying to model them will inevitably end up with obscure code that no one will ever understand either. Especially as legislation and accounting practices accrete in the future, with special cases for every single decision.
