Nah, if we allow virtual experiences, than any model naturally becomes the block universe.
I believe, that question of experience is still unsolved. Why do we seem to live in a world made of matter and governed by physics? Is it the same for people that are simulated in a computer? Is it the same for people that are not simulated by a computer (because it is plugged out)? How do they perceive if the data is mangled? Etc. BTW the block universe also needs to solve this problem. But in order to not to be in a block universe, we need the answer that being material based is different than being simulated on a material based simulator, or not even being simulated, just the possibility of it.
@sobellian: relativity doesn't need the block universe. It works perfectly fine if people just get shorter when they speed up. Then the simultaneity of events in a frame is not the same as being in a slice.
