No, copyright law is about the exclusive right to make copies, among other rights. In US law this is 17 USC 106.
The reason making a single copy for personal use is generally considered permissible is because: (1) it may be fair use under 17 USC 107, (2) the copyright owner will probably never find out, and (3) even if the copyright owner found out it probably won’t sue over one copy.
