It's certainly maddening - but remember that the GIRM is designed to apply to a mission church in Africa's interior as well as a parish church in a wealthy American suburb.
As I hinted above, in America such things shouldn't even be an issue: every parish in America can afford a chalice lined with gold.
In an African mission, the rumor of a gold-lined chalice might encourage an act of greedy violence against a priest.
Common sense should be applied in using the GIRM - leeway afforded to the unfortunate and oppressed shouldn't be twisted into a political weapon by lazy liberal priests in America.
