Well, you do seem to want to solve the problem with your idea about an artificial simulation.
But why invent the argument ? Current understanding perfectly explains why we can't perceive everything.
This reminds me of a funny thought that I related to a friend of mine years ago: What if our reality is actually being generated artificially by beings holding us in a type of detention facility. that none of this is even real. Any one of us could be sitting in a dank holding cell on another Planet.
