Most desktops that have a lot of storage have it filled with
multimedia, which is highly resistant to data rot, the OS can be
reinstalled, this is not a significant issue to most people.

I'm specifically talking about the case where a desktop PC is converted
from JBOD to ZFS without any redundancy.

When you lose some files from a directory it often renders others
worthless, for example losing a third of the episodes of a TV series
can be much the same as losing all of them. When a disk fails with UFS,
the directories on the other disks are completely unaffected.
