That means if I get 12 people that agree with my methods and interpretations I can put the entire remaining 80,000 appraisers out of business
No, If you can get 12 out of 80,000 you can win once, on one day. That will be one down and 79,999 to go, assuming you are not reversed on appeal.
The AI comes down on both sides of the issue.
Oh what else is new. The AI is nothing but a bunch of appraisers. And so are we.
How many PhD, MAI, CRE authors have to critique the cost approach before a single one of these discouraging words is ever heard in the AI text? Dr. Dotzour, SRA published an empirical study (that means from real appraisal reports) on the cost approach and found it was not a reliable appraisal method. Not that this is final and definitive, but at least one of these noted authors rates a mention before too many more decades go by.
IMO - After your article in Harrison's pointing out the errors in the AI Workbook, you are more of an authority on correctly employed recognized methods in sales comparison than the AI text. Think about it. In the information era, where one man and his computer can topple empires, you caught the emperor with his pants off. Even as far back as the 10th edition there was 37 pages on regression – IN THE APPENDIX!!!
The significance of this may be lost on some folks, but not on your "peers."
So stop fretting about USPAP. You do not need to worry about "them." "They" need to worry about you.

BTW, I would debate that the new SR 1-1 is really "binding." Each key rule has a
departure mechanism built right into it in the form of "given the scope of work necessary." Read the Instuctor's Manual. Now there's
explicit relativism. I was only giving you pragmatism.
