What if your drive has a fault, and that file gets corrupted?  You've now
lost your entire backup, rather than just the file that contains the bad
sector.
What if you want to restore the backup to a different sized drive?
What if you want to easily recover one file?  A directory?  N directories?

There is a time and a place for a low-level approach, but it's not always
the correct answer.

[1] You could mount the image, but how long will it take vs. browsing into
it and copying it, or restoring a file from an indexed backup?
