The rest of your comment doesn't back that up. The hyperloop potentially solves the problem of air travel out competing railways even though air travel has enormous environmental costs and generally sucks due to overhead in transits and small cabins.

The problem with hyperloop is as you say actually building it. But that doesn't mean it doesn't solve a problem. It just means it has its own practical problems that aren't even technical.
