You extract Ar from air by refrigeration and compression of .. well, air just like you extract Co2 from air It is IMPOSSIBLE to run out of Ar.
From Wikipedia: Industrial
Argon is produced industrially by the fractional distillation of liquid air in a cryogenic air separation unit; a process that separates liquid nitrogen, which boils at 77.3 K, from argon, which boils at 87.3 K, and liquid oxygen, which boils at 90.2 K. About 700,000 tonnes of argon are produced worldwide every year.
Yes, you do need energy to compress and super-cool the liquid air down towards -200 C, but other than that, it is a simple enough process.
Will the EPA regulate the CO2 fire extinguishers next? After all, they DID all but ban the more effective commercial fire-fighting gasses even on Navy ships where winning in combat by fighting fires and explosions is evidently less important than preventing the hole in the ozone layer.

Eventually EPA will ban Oxygen. It is dangerous. It reacts with many other substances. It contributes to the forest fires that destroy so many trees every year.

Let’s just make it simpler for everyone & ban the EPA.

They are trying to ban welding!
Nothing but mild steel can be welded without Argon.

The EPA should be threatened with a close down
To: Robert A. Cook, PE
Anyone who welds Aluminium or Stainless Steel will be familiar with Argon, which is used with MIG and TIG welders, to blow oxygen away from the electric welding arc, to prevent oxidative damage to the weld joint. Any effort to regulate the use of this harmless substance would do incalculable damage to American industrial competitiveness, for no benefit whatsoever.
