Great post. I just wanted to add that space and energy could very much be emergent phenomenon, as well. Take for example Wolfram's conjecture that the universe might be modeled as a causal network [1], in which our 4D spacetime emerges from the connections between nodes, and energy/particles emerge from the complicated dances of knots in the network. It might sound pretty far fetched, but it seems to me at least as reasonable as the universe being modeled by a small set of equations.
