He does make the rather blithe assumption that mathematics is somehow real, and not an idiopathic artefact of our cognition, as much as the apparently respectively static and dynamic nature of space and time that he notes most posess. Perhaps mathematics is also a stubbornly persistent illusion.
Me, I see the universe as information, and everything else flows from that. We are needles scratching out the tune from a hyperdimensional record. Our mathematical laws may well be encoded within that information, or are representative of symmetry within it, which is also reflected on the structures and strictures of our minds, but I see mathematics as effect rather than cause - not that there's really such a thing as causality, either, if you stop thinking of "the arrow of time" as being a thing other than how we experience spacetime. Causality is as human an invention as sunrise.
Then again, I'm assuming that information can exist.
Perhaps it's turtles^W simulations all the way down.
