Well, sure, but all the ugly generated labels and such are there when
you have to read the listing rather than the source. And there are
times when you have the offset where something program checked, and
the source just won't do.

Not that I don't use structured (structuring?) macros; I do and they
are great. But using both source and listing is like listening to a
piece of music as a whole or as its component parts; it's difficult to
do both at once.
