I don't agree. The existence 3^^^3 people, or 3^^^3 dust specks, is impossible because there isn't enough matter, as you said. The existence of an event that has only effects that are tailored to fit a particular person's idea of 'bad' does not fit my model of how causality works. That seems like a worse infraction, to me.

I'm not sure I agree, but "which impossible thing is more impossible" does seem an odd thing to be arguing about, so I'll not go into the reasons unless someone asks for them.

However, all of that is irrelevant, because I answered the more "interesting question" in the comment you quoted. To be blunt, why are we still talking about this?

I meant a more generalized you, in my last sentence. You in particular did indeed answer the more interesting question.
