Earlier quoted context omitted.
It’s not halfway across the globe. Not even quarter way. Meanwhile, the US one dollar note is made with flax imported from Belgium (also not halfway across the globe, but farther away).
Why not locally sourced? I mean it's very possible flax isn't native to the Americas but it seems wasteful to source something from abroad. And while 100+ years ago it made sense from a logistics point of view - use hard to find materials to fight counterfeiting - I don't believe that's a valid argument anymore.
It's been grown in that part of Europe for thousands of years and in the 19th century it was a major industry there. I don't think it's still a major crop in Belgium (too low margin) but the company in question is entrenched now.
