Natural monopolies should be centrally planned, because in this case the market competition is between nations on the basis of which one is an efficient and therefore cost effective place to operate. Companies don't set up competing mail rooms in the same building, that would be insane. It's less obvious at a national scale but economically just as silly to try and introduce competition where it would not naturally exist. The same principals also apply to railways, water, roads and phone lines.
