Abstract: The PBR-theorem aimed at proving that the wave-function has to represent objective features of a physical system. There have been many attempts to interpret the wave-function as not representing the objective physical state of a quantum system by abandoning one of the assumptions of the PBR-theorem. I argue that each theory that violates either of the assumptions meets unsurmountable problems. The most severe is to give up objective reality.
