Doing it with a plough might work, but copper is a lot more robust than fibre (especially for fairly vague definitions of connection quality). Running it alongside the power lines is probably the most cost effective way to do the planning, but you still have to pay someone to go up the pole and add another one. Again, you're not saving a huge percentage by already having the poles (probably enough to pick it over trenching though). Long-haul fibre can span transoceanic distances. If you have dispersion-compensating segments you can get it up to a few hundred km without significant bandwidth loss on the to-the-home scale.
