Maybe I worded it wrongly, sorry. I didn't mean "why does it matter?" as if people shouldn't care about those questions. It was rather a rhetorical question, to show that the "simulation" might not depend on anything "outside the simulation", so the questions would simply make no sense.

Then again, this was just one of many variants of the simulation hypothesis, just something unfalsifiable that shouldn't be taken too seriously. :-)

Well, a better conclusion is, if it matters to you, then it matters to you.

You can't make a more general statement of meaning out of your very specific declaration.
