One major advantage of RAW, in addition to the previously mentioned
ones, is that you can easily edit the RAW image, non-destructively.

You can edit anything non-destructively.

Right, but you can't save it back to Jpeg non destructively, so why start
with a lossy Jpeg in the first place?
I can't see the point myself since you can easily set up PS or LR to
automaticly apply your camera settings when you open a RAW file if that's
all you want to do. If I really needed to print direct from the camera I
can save RAW+Jpeg, never do though.

I know what they mean by "non destructively" - that all of the edits are
saved in layers and can be undone at all times. But all I am saying is that
I do not edit on my JPGs and then save it back to the same JPG file I
started with - I save it as a new file, a TIFF, so that the original is
still there.

By starting with a JPEG you have already lost information, all you have
done by saving as a TIFF is to suspend further degradation.
If you are making that conversion, you have an inefficient workflow. It
is far better to start with a 16-Bit full data, RAW file to adjust,
than an 8-Bit TIFF which is already missing data created from an 8-Bit
JPEG.

You need to educate yourself with regard to file types and how various
processes effect them. You are functioning under an incredible cloud of
misinformation.
