This is true, assuming that the UD is running, or that some other generator of every possible program is running. Now, I am attracted to the idea that every computation is in fact "run" by virtue of its existence as a platonic object, which is in part (I think) step 8 of the UDA, but I am not completely convinced by this. What if there is a single, finite physical world containing brains and digital computers, and only these devices are actually capable of performing the kinds of computations needed for consciousness to occur?

Again, you could not know this for certain. The world may just be an illusion created for your benefit five minutes ago, even if there is no UD or its equivalent. However, in general we should have a good reason for saying that things are other than what they seem, or else we go crazy. What it comes down to again is: how can we be sure that the UD is being run?
