i'm not sure i understand your point.  the copy command does run as
the postgres user (since postgres does not run suid root and therefore
cannot become you) so all directories to/from which you copy must be
writable/readable by the postgres user.  also the target/source directory
will be on the server machine, not the client machine.

one could get around this by shipping everything to the frontend app
and having the client side of libpq write the file.  postgres doesn't
do that.  since the code exists for copy to/from stdout/stdin this 
wouldn't be too hard to add (in principle).
