But the view from the inside points of view is different.
You appeal sometimes to the block universe view of relativity theory --
the block is static, but observers inside experience time. In general
relativity there are difficulties with the definition of a time
variable, but in special relativity, time can be defined as a direction
in the block. Then slices through the block orthogonal to this direction
give the experienced moments of time.
I do not think that you can do anything similar with Platonia because it
is not a well-defined four dimensional object with a defined Minkowskian
structure.
If everything is to 'happen' in Platonia, you need to specify a temporal
variable. This is not trivial, and I have not seen any convincing
explanation of how you intend to do this.
