The journal is absolutely required to preserve the integrity of the
file system's own on-disk data structures after a crash. Even if
you've got a trustworthy file system checker (there are surprisingly
few of them, especially for advanced file systems without fixed data
structure locations), running it after a crash usually leads to
unacceptably high downtime.
