The claim was that it’s harder for the USA to get the required levels of unobtanium than a smaller country because it needs more.

In reality the USA has more purchasing leverage because it can exploit (and is exploiting) geopolitics, and can obtain at least as much reagent/unobtanium per capita as other countries right now.

To put it in terms you might understand, the USA has a better ability to source reagent than you do - see if you as an individual are able to procure even 1 litre of the stuff!
