Yeah, compared to other noble gases, it’s pretty rare, and we don’t produce very much. If I recall correctly, the 900 kg loaded on the Psyche spacecraft last year represented about 10% of the world production.
That doesn’t make it rare. It’s just a byproduct that is produced in large enough quantities for other uses without specifically cracking air to produce it rather then oxygen and nitrogen.
