Simple answer; the currency system of Creation was invented before the Order-Conferring Trade Pattern was retconned in. The Order-Conferring Trade Pattern is rather a bloated tumour on the setting that people keep on trying to make into more than a mild curiosity.
Moreover, I note, silver currency is an insistence of the Guild in canon. The Realm wants everyone using their jade currency as the international currency of commerce because it gives them power over them. So, no, even there it's not the Realm's fault.
Well, actually, in such a case I think the Realm would still have at least some share of the blame. "I politicized an important action to hold back the Wyld [If you accept the retcon] so much that people will use silver rather than becoming even more beholden to me" doesn't exactly speak volumes in your favor?
That said, the simplest explanation is the best: it's something retconned in, so should be ignored unless you want to for some reason. Or downplayed at least.
