I thought of the similar thing before, including all of the details they mention, and I agree. (Of course you still might not konw what it is unless a simulation can be made, but it can exist (mathematically) whether or not a simulation is made.)

Furthermore, I think that anything existence (including mathematics, physics, etc) are by relation to everything else that is existence; there is no such thing as an "existence" that is truly independently from everything else, including mathematics (and, the various possible mathematical structures, and physical universes), etc. (If it is truly independent, how can numbers be prime and composite, and how can objects collide with each other, and how can planets moving around the Sun by gravity, and how can people have ideas about the gods, etc?)

(However, there is then the consideration if such a simulation is being made which is then being interacted with by outside (e.g. as in Star Trek); in that case, it is I/O, so you can make "Mathematical Universe Hypothesis with I/O". This could be called as a kind of nondeterminism, I suppose; although, a constraint may be produced by their combination.)
