And it just so happens that the amount of bitul needed to physically do
away with kashrut problem also does away with the timtum problem (or why
does bittul brov or bshishim work, and why any difference if it is
objectively poison)

BTW I don't think anyone holds the non-Jewish wet nurses milk is not
kosher - just not recommended due to timtum.
