Too expensive and hard to maintain. You can get pretty good speeds with traditional rail, in western Europe there are trains reaching 200-250km/h.

300-350km/h actually. Although most places indeed average 200-250 on high speed lines (especially Germany).

Because having cryogenics for thousands of miles of open-air track is kind of hard

Sure, but if we just didn’t do stuff because it’s hard, then we’d never chosen to go to the moon. That guy on TV said so.
We might not do stuff because it’s an awful and downright terrible idea, but both looking at humanity as whole and my own personal experience, that doesn’t seem to be much of a deterrent either.

We choose to build from steel and other things because they are hard

The Japanese SCMaglev only has the cooling stuff on the train, not along the entire length of the track.
And I think there is a “high-temperature SC Maglev” in development in China too.
