I assumed scrubbing every two weeks (as I do) should reveal read problems before any drives fail, at least in the common case. Maybe there's something important I'm missing?

No, you're not missing anything. Scrubbing catches it all. Seems your parent is concerned about errors between last scrub and a failure.

This is why I have a backup system that I zfs send to.
