I disagree with your definition of tag. I view a tag as a 'label' is
in VSS, a label is not a copy. A label marks the repository at a
particular time. I can make a copy of the trunk without subversion's
copy feature if I want. But I can't put a label on the trunk at a
particular time in its development, subversion doesn't appear to
support that. Moving the label to a different revision should be
possible but hard to do my mistake.

But the problems go deeper than that. When you make a tag and then
commit to it, where is it recorded which revision of the tag is the
"real" version? I.e. If I make a tag called "Release 1.0", but then
someone commits to it, was "Release 1.0" the first revision of the tag,
or the later revision?
I have no problem with the implementation of tags as cheap copies, but
the interface could be improved out-of-the-box if subversion had
built-in support for read-only copies and the link between the copy and
the original was more obvious. A history of the trunk should show when
tags were made and what the paths to those copies are, if it doesn't
then the trunk really isn't tagged is it?
