Of all the gases why Nitrogen? Argon is more commonly used for kill bags, I think.
Atmospheric prevalence?
Pretty sure argon is one of the most expensive gasses to harvest/mine.
Argon is the third-most abundant gas in Earth’s atmosphere, at 0.934%.
Argon is used in welding and costs slightly more than oxygen.
But is oxygen cheap? Oxygen is easy enough to filter out of the air, but storage and shipping are not simple. By contrast as you filter out oxygen, you’re leaving basically pure nitrogen (sure with argon and the other various gasses in negligible quantities.). I truly don’t know. Would be happy to be educated one way or another.
