Hyperloop would require massive property right of ways and would involve incredibly complex law making, even run 30 feet underground. That gets government involved and it's slow scheduling. With the government involved, the need to accommodate "everyone" would force the system to include "ghetto stops". Now it's no longer an express, just a local. Max Speed makes no difference. Might as well re-fund Amtrack, or even run Greyhound as a public utility. NEVER gonna happen
