Need a balun?

Let's say I have a perfectly balanced dipole with a feedpoint impedance of
72+j0 at my frequency of interest.
I connect a perfect 72 ohm coax (an unbalanced connection) to the feedpoint,
and drive the antenna system with an unbalanced 72 ohm source.

Since the power sent to the antenna is not reflected, do I need a balun?
