Causal Structure and the Delicacy of Holographic Arguments for Unitarity

I examine Marolf's influential argument for the unitarity of black hole evaporation based on what he calls a holographic argument for boundary unitarity.

I draw out a hidden assumption of the argument, that the causal structure of the interior must be nice in a particular way. I conclude that his argument thereby either begs the question or else necessitates a peculiarly strong and promiscuous global non-locality of spacetime structure, which I find hard to accept.
