_If_ people included the class attribute you've added above, this isn't
destructive markup anyway, at least not in the strong sense we've been
describing.

In the larger case, however, I think this argument obscures the difference
between:

Semantics have been removed
            and
Semantics we can't understand

I can send out documents using CSS and any DTD I want, and you can see them
in a browser.  Machine-readability may be difficult if the program hasn't
been trained for the semantics, but at least the semantic markup is there.
Humans can still figure out 'lastname' and 'firstname' (cultural issues can
cause mixups, of course) and provide the necessary interpolation.  It's not
as good as a standardized DTD we all know, love, and come to expect, but at
least we can still provide mapping for it by hand.

Even in harder cases, say where the semantics are in another language,
there's still hope through traditional dictionary approaches and other
interesting possibilities, without having to analyze the entire document
and make guesses based on formatting and further guesses about what the
labels are.  

Yes, we need controlled vocabularies.  Their absence, however, does not
suggest that we need to rush our data to a controlled vocabulary that only
describes formatting.
