Where exactly is one supposed to put PTFE tape if not on the thread of
compression fittings?

Its real purpose is when you have to make a joint that requires a seal
to be made on the threaded part of a connection.

A compression fitting makes a seal between the pipe and casing by use of
the olive - the threaded part itself does not even come into contact
with the water.

...in Theory. Of the olive seat/olive is less than perfect then water
can seep past.
