If it really is beneficial, then Elon Musk and the share holders, should use their same influence they have on the government, on the financial institutions that exist to acquire low interest loans. There is of no reason, that the tax payers should be forced to support the risk or even a project that few people under the upper-middle class will benefit from. There is no reason that Elon Musk should be subsidized to create a private monopoly of transportation––quite contrary, he should be paying the government for the externality caused by being privileged to the exclusive right of the vast common land underneath the states; a common land that other tax payers are now deprived from. Most citizens of the USA don't even live in the city, especially the ones who you claim would benefit from it. They already live in cheap housing in New Jersey 30 minutes away.
