It kind of sounds like you’re talking about it purely as a thought experiment or as something to inspire other philosophical thinking. But I think the issue most people have with the simulation theory is when people think that it’s actually the way that the world is or think that it’s worth investigating the way that the world is just because it theoretically could be the way the world is. But theoretically the world could have been created by the god of the Bible or any of the other million explanations proposed by the million other religions that have existed. Almost every religion proposes a hypothesis that could indeed explain reality, but just because it could explain reality doesn’t mean it’s reasonable to investigate it.

I agree with you that all the questions you raised are interesting and worth thinking about, but none of that really relates to thinking that we actually live in a simulation. You’re just using the idea that we live in a simulation as inspiration to start thinking about these other ideas. But actually thinking that we live in a simulation is much less reasonable.
