You're still fixated on the implementation details. What you really
want is to preserve the state of the code at a certain point in time.
Whether you do it by labelling it or by taking a copy is immaterial.
As it happens, svn copy does not actually create a physical copy of the
files unless you change them in the copy. In terms of implementation
you have just labelled it.
The only real criticism I see is that it's hard in subversion to make
the copy read only.
