Above comment said it was not scarce, not that it wasn't valuable.

  If it is not scarce - the value is low.

    Breathable air is pretty valuable, at least for me. And it's definitely not that scarce on this planet.

    Well it was. Supposedly it cost about the same as wheat by volume (and salt is ~50% more dense). So it was dirt cheap.
