Cecil,

You may believe it is obvious, but it is not quite clear what you are
trying to show in that figure. On the left side, traveling wave, it
appears that "magnitude" means Io. On the right side, standing wave, it
appears that "magnitude" means Io cos(kx).

The gist of your position seems to be that somehow the traveling wave is
more powerful, or at least different, since the area under the current
magnitude curve is larger. In reality, however, it is necessary to pick
a single time at which to compare the two cases. It is of little value
to look at some sort of overall envelope for the traveling wave. The
correct magnitude of the traveling wave never has the shape of the
overall envelope. Pick a single time, say when wt is equal to zero or
equal to pi. Then compare the curves. In fact, if you pick any single
time for the left side the resulting curve shape will look a lot like
the right side.
