That's because the copyright has ceased: the contents of the book are
no longer subject to the protection of copyright law.

Because its copyright has not ceased.

This permission is bound to actual copies.

This makes explicit that the GPL is valid only for licensees.  You
can't become a licensee without acquiring a physical copy: that's what
copyright covers.

What about "licensee" don't you understand?

The GPL could state no such thing even if it wanted to.  Its reach is
to the owners of copies.

The ink manufacturer can't grant people access to my letters, and the
GPL software manufacturer can't grant people access to my software
media.  Once I pass copies on into separate ownership, I can only do
so under the GPL (or the default provisions of copyright law).  But
internal use does not amount to that.
