> To do so, of course, he'll need to reduce the costs of tunnel boring by an order of magnitude.
That's easy. Construction projects these days are horribly expensive because the entrenched companies usually overcharge the state (and in some cases even private customers) and redirect that money into the coffers of corrupt officials (e.g. Odebrecht, http://www.spiegel.de/politik/ausland/odebrecht-gigantischer...). Also, in most state founded projects there is no risk control or project management so companies end up fleecing the state - just look at the Berlin Airport for what happens when oversight, competences and reports are lacking. Not to mention that "pay by work hour" contracts almost automatically lead to slow work, overtime and delays because the state pays the losses of inefficiency compared to a contract "here's 20B €, build this tunnel, there won't be any additional money except in case of unforeseeable stuff like geological issues".
Musk on the other hand does not have these problems because he does not (neccessarily) need profit, or at least not illegal profits. Also, his companies are massively vertically integrated, which means that he won't get fleeced by suppliers, as well as horizontally integrated - I highly believe that the knowledge present in SpaceX can also be used for creating drilling rigs.
