"Optimal", in terms of the original question posed :

Nowhere in that problem statement do I see any desire that
the text be separated from any preceding text by 2 em of space,
or indeed by any space at all.  My own solution is open to
criticism on the same basis, in that it forcibly inserts
the space of the line. The following version attempts to
rectify that, although it has not yet been as rigorously
tested :

    \newskip \myskip
    \def \HardRight #1%
            {\myskip = \lastskip \unskip \nobreak \hfil \penalty 50 \hskip \myskip \hbox {}\nobreak \hfil #1%
                \parfillskip = 0 pt \finalhyphendemerits = 0 \par
