The $/launch numbers don't account for the refueling flights, which will be necessary to get to and return from the lunar surface. That would bump that number up to ~$10m/$20m or so. Still ridiculously cheap and not likely to be anywhere close to the price charged as it would absolutely sink the rest of the market, which SpaceX is not interested in doing.
