i like your train of thought bomb, until the conclusion.
but in all the cases you mentioned until the one with no worm at all, there is strong EVIDENCE that you have recently consumed a portion of a worm. in the case of no worm at all there is no evidence whatsoever. you actually stated this yourself so i dont understand why you actually posted this.
your original question as to whether this was profoundly brilliant or the opposite seems quite clear.
no one worries about what might have happened if there is no significant indication that it might have. no one worries whether or not their dinner last night contained a delayed action poison which will be suddenly fatal in 24 hours. or at least they shouldnt, unless there is an indication that this might have happened.
