I covered that on the next few lines, which you choose not to quote.

That's true, but it would have told you about any error in any
accessible data _and_ also told you which file or directory was
affected if that was the case. If the error is in an inaccessible
portion of the drive and the system is working normally aside from a
note in SMART data, then it would stand to reason that the error would
be in an unused location; thereby not likely to affect usage (because
a known bad spot would be reallocated elsewhere by the firmware on the
next write).
Also, badblocks too will only deal with user-accessible blocks; if the
drive already had remapped a bad location, for example as a part of a
write to an identified bad block, the original error would be
invisible to badblocks even if it still was an error.

After restoring your most recent backup, consider doing a fstrim to
TRIM unused blocks.
