there is no copyright protection; therefore the scope of any existing copyright is nothing, and you can not change that by instituting your own copyright on an uncopyrighted work. note though that this is unrelated to licence, in that i can take a work that is in the public domain, make a verbatim copy, and put that copy under shrinkwrap licence. a licence is a contract, and if i agree to the licence i must abide by its terms. of course, if i were to discover that the work is actually in the public domain, i could copy it anyway, and unless the licence said something of the form "in exchange for the cardboard box this work came in, i agree never to make a copy of the work in any way even though it is in the public domain" nothing could be done about it. --p.
