Earlier quoted context omitted.
So far, in this brief comment and a brief comment above, you've mentioned Goodhart's law, the McNamara fallacy, and the Munchhausen trilemma. I know nothing of any of these. I think that you would communicate better if you avoided such references. I'd even venture to suggest that your internal thoughts might be improved by not shoving arguments into such pre-defined categories.

Here is aa equivalent statement, as terse and clearer, than the comment you made above.
