Stathis,
I would not deny causality in such a universe so long as the logical
structure enforces the Life rules (meaning, the next level in the
stack is *always* the next life-tick, it couldn't be something else...
which is true by supposition in the block world).
Perhaps that still counts as a magical requirement for you, though.
