Ask your local FAA Inspector... I see no problem with having
a passenger put their name in a book as a passenger, but by
law (FAR) only an authorized instructor may endorse (sign)
for instruction given.

Wrong. By *regulation* (FAR), only an authorized instructor may endorse for
instruction given *and used for the purpose of meeting the requirements of
the regulation (FAR)*.

Anyone can sign anything they want. Most things require a CFI if you want
the endorsement to be useful for the purpose of meeting the requirements of
the FARs, but that doesn't mean someone who isn't a CFI can't sign a
logbook.
