Thank you, Vladmir, for your honest criticism, and more is invited. However, this "Worst argument in the world" comparison is not applicable here. In Yvain's post, he explains:

The opponent is saying "Because you don't like criminals, and Martin Luther King is a criminal, you should stop liking Martin Luther King." But King doesn't share the important criminal features of being driven by greed, preying on the innocent, or weakening the fabric of society that made us dislike criminals in the first place. Therefore, even though he is a criminal, there is no reason to dislike King.

If we do an exercise where we substitute the words "criminal" and "Martin Luther King" with "virtualization" and "death", and read the sentence that results, I think you'll see my point:

The opponent is saying "Because you don't like death, and being virtualized will cause death, you should stop liking the idea of being virtualized by an AGI." But virtualization doesn't share the important features of death like not being able to experience anymore and the inability to enjoy the world that made us dislike death in the first place. Therefore, even though being virtualized by an AGI will cause death, there is no reason to dislike virtualization.

Not being able to experience anymore and not being able to enjoy the world are unacceptable results of "being virtualized". Therefore, we should not like the idea of being virtualized by AGI.
