There already _are_ thousands of such assertions. Either people are
largely untroubled by ambguity, or, in practice, ambiguity isn't the 
disasterous problem you're making it out to be.

Why are they fools?

Well, this is the status quo, and the prospects of changing it strike
me as fairly slim. So if you're right that this renders metadata
useless, we may as well pack up and go home.

My argument against this counsel of despair is that should we 
recognize ambiguous references rather than bury our heads in the sand, 
and look for mechanisms which make the problems go away, or at least
make them relatively harmless.

Some of those mechanisms already exist (eg. Accept:, or the fact that 
cars aren't electronically retrievable eliminating them as possible
referents in retrieval contexts), and others could be invented.
