I'm pretty sure I understand your specific argument regarding dust theory. I'm also pretty sure that the reason I'm not upset is because I require observables to actually care about things like that. You're worried about an idea/argument that has no backing evidence, makes no observable predictions, and is unfalsifiable - no matter how horrible it sounds, it isn't sane to fret over that sort of thing.

Also, I would encourage you to spend some time on the concept of identity for yourself. Even if your idea/argument did have backing evidence, it wouldn't be horrible to me because I allow distributed identity.
