Nitrogen gas is safer to transport than air. It's by far the most common gas bought and sold in industry and elsewhere (anyone needing a lot of compressed air just buys their own air compressor), and since it's typically collected as a byproduct of a more useful chemical reaction, its price of collection and purification should be comparable to air.
All I'm saying is I don't know if air is cheaper, and I don't see any reason to say it is or isn't.
