Copyright law doesn't care whether something is an original -- derivative works are also protected. Copyright protects creative works, however original, where creativity is defined by some semblance of originality (in content, arrangement, form, etc).

You can totally ask an author for a spare CD; however, he's not obliged to give you one.

Also, you are mixing up contract law (licenses) with copyright law ("default" law which applies in the absence of a license or certain licensing terms).
