You are starting from the position that the Elonrail is a good thing, or a practical thing, or even a feasible thing.

I start from the position that it is none of the above. It is a boondoggle, like the hyperloop. It solves nothing and the proposal as presented only raises numerous problems that Elonrail fails to address. Which is pretty typical of Musk these days: present a shiny new idea, not fully thought out, as if it were something innovative, take credit for it, and then let other people do the work of actually figuring out whether it's even possible to implement.
