My point was that electrons traveling through copper have to go through impurities, friction, collisions and other things that slow it down. Thus, during the process of travel, the signal may have to be boosted to keep it going. Copper is also required in large amounts to carry high volumes of information.

For high voltage, cooper is the best overall thing that can be used in bulk at a reasonable price. Transmission cables however use aluminum conductors or a mixture of cooper and aluminum because of weight issues.
