Yes, so it’s a testament to how ridiculously ideal for public transit this fictional scenario is that in this fiction, hyperloop might be a worthy investment.

One of the reasons hyperloop was a scam is that they never really tried. There were some very public-facing stunts, like the design competitions, but they didn’t do the SpaceX thing of throwing a couple billion dollars worth of government subsidies at failing prototypes until they started working.

Another reason is that high-speed rail makes a lot more sense when you have regular stops like a real-world HSR line would. Accelerating and decelerating take distance, so the faster you go the longer you need to go between stops for a top speed to matter.

And another reason is that high-speed rail didn’t exist yet, and this was presented as a better alternative. If you already have the best open-air HSR money can buy, the next logical step is to stop having it be open-air.

Though, saying that, an atmospheric pressure pneumatic tube where the surrounding air is brought up to the same speed as the maglev train would probably make a lot more sense than a vacuum tube.
