Because there is only one primitive - an isolated point and one
source of "meaning" its position in its region. If the region has
only discrete locations then one can encode a state of this type of
universe directly as a string of 0's and 1's. 1's mark the position
occupied by the point in its region and 0's mark the empty positions
in its region. Each region has its own sub string consisting of 0's
and a single 1. [quite compressible] Once you have a particular
Huge Lookup Table [HLT] you have how a particular universe will
evolve from this state. Attach the HLT as a prefix to the string.
The computational resources required are a large memory as with any
model of a universe such as ours but a simple processor.
Generally I think each region can be updated asynchronously and
entanglement may be where you do it synchronously for selected regions.
You can "expand" such a universe by just adding regions.
Of course in the real universe the HLT is immediately presented to
the point via the local "curvature" [shape] of the grid and
"observations" by large dances [observers] is just an interpretation
of the large scale shape of the grid.
Any model keeping track of the particulars of an ocean of particles
[or strings] and determining the next state with a bunch of force etc
formulas over a continuous 3 space plus continuous time seems far
more complicated to me even when you get rid of the computer.

Why is this the simplest? It looks horrendously complicated to me.
