I think a global unique-name model is sustainable only in a very fragile sense: if everyone cooperates and nobody ever makes a mistake or gets confused, then it will work. But one error, anywhere, could make the entire edifice crumble, since nobody could then rely on the global assumption being valid. In fact, I will undertake to be the fly in the ointment, and will offer a universal unique-name-wrecking service by generating copies of RDF webpages with just the names changed.
