You are sure right that DBMs, like BDB, seem to fit the problem well.
On the otherhand maybe the seeker needs multiuser access or wants to remotely connect to his data.
We don't know that.
After all RDBMs provide much more services and usually fit smaller problems too, often also avoiding scaling problems.
So the general advise is often to use RDBMs where DBMs would suffice, that is not always based on a misunderstanding, maybe even more often based on the simple fact that people deal more with RDBMs than DBMs.
People are running multiuser operating systems for mere desktop usage after all. And many are happy with that, even so a single user system would suffice.

Another approach that often is forgotten is to write your own storage method, which given the seekers description doesn't seem to be out of hand and could well result in the most performant solution.
