You still are not understanding at all what Bostrom was saying...
Exactly 50% (or any amount whatsoever, including 0% or 100%) of
posthuman civilizations running simulations is perfectly compatible
with his argument.

This percentage being significantly above 0% just means that option
(2) can't be true, in which case (1) or (3) (or both) is true.

Would you also like to claim that "x or y" implies mutual exclusivity?
Have you ever studied logic, and noticed how words are not always used
in the exact same meaning that many people use them in their everyday

It is extremely obvious that Bostrom did not mean mutual exclusivity
by saying "unless". He even made this very explicit in the previous
sentence, by saying "at least one"!
