Maybe "intended to decline " or "managed to decline" would be more accurate than "designed to decline", but I think that's rather splitting hairs.
Gold bugs often claim that they want a hard fixed currency that doesn't decline in value over time. But it's only the decline in fiat value that makes the gold price go up. If fiat didn't decline there would be no point in buying gold and gold bugs would just be old fashioned misers stacking fiat, sitting at home counting their piles of notes and coins like Ebenezer Scrooge.
