So do you want to correct my incorrect conclusion or are you happy to just call it a day :P

The contradiction was in saying the simulation hypothesis was fundementally unfalsifiable, and then pointing to its falsifiablity as a reason to prefer it to other belief systems. Your edit made it more clear, but there is still a contradiction there.

Given that a sibling comment is expressing very similar criticisms, I think my interpretation of your argument reflects something present in your text. If I am mistaken, please help me understand your point of view better. This is what good faith discussion is about. No shame necessary.
