To clarify, there's no "my simulation" and "your simulation" in the present discussion. What's potentially being simulated is the entire universe, with no privileged viewpoint. That the universe is being simulated simply means that the laws of physics of "the universe" have been implemented on a computing device that exists outside of "the universe" (and which therefore does not itself necessarily obey those same laws of physics).

The Simulation Argument (to the extent it applies to anything at all) applies at least as well to solipsistic simulations where all that is simulated is one observer and their personal observable universe.
