If that can happen then you can lose your text-mode config files too.
Sorry, that argument doesn't convince me. :)

Sure.  You assume that the database software is reliable.  That's why
you use the standard software components rather than rolling your own.
If you have filesystem, fsck or application bugs, then whether your data
is stored in a database or as plain text has absolutely no impact on
your ability to recover --- it's not a valid argument against using a
journaled database.  (If you don't trust libdb2's recovery, then that
_would_ be a valid argument.)
