Helium

Helium is not that rare even outside geological gas reservoirs. It's more common than krypton and xenon in the atmosphere.

Cheap helium may go away in the next fifty or a hundred years due to exhaustion of those underground reservoirs but it will still be available at a price.

Presumably at a worst case you just throw energy at the problem and freeze air or some other way of extracting it from the atmosphere.
