Why?

  Poles can and will be damaged due to external forces (car accidents, lightning strikes, wind, snowfall) all the time. A properly buried cable (buried below freezing depth) will last as long as no one manages to hit it while digging.

    At amazingly huge expense. It's way cheaper to re-string it every few years on the pole when it gets damaged then to avoid the myriad of other cables already underground.
