abstract = { Clifton, Bub, and Halvorson (CBH) have argued that quantum mechanics can be
derived from three cryptographic, or broadly information-theoretic, axioms. But
Smolin disagrees, and he has given a toy theory that he claims is a
counterexample. Here we show that Smolin{\textquoteright}s toy theory violates an independence
condition for spacelike separated systems that was assumed in the CBH argument.
We then argue that any acceptable physical theory should satisfy this
independence condition.
