And then you remember that there are 10^23 particles in a single gram, which is in orders of magnitude of all CPUs on earth. We're as close in orders of magnitude to the size galaxy 10^20 as we are to the nucleus 10^-18. Or put it another way, there is the same amount of units of proton radius in 10 meters as there are 10 meters in the entire Galaxy. Another way to look at it, is that the most plausible assumption about self- simulation is that it is maxed out at some constant efficiency, say you need a system that is 10 times bigger. Then the entire babushka of simulations are merely a geometric series, and in fact you're most likely to exist in the outermost babushka except the most efficient of all simulations. If you assume the world is a simulation, it must be an imperfect simulation that shortcuts away several orders of magnitude compared to whatever it is meant to mimic.
