Where did the topic of a national license come from? I've never once advocated for anything of the sort.
I may have failed at it at some point, but my intentions with USPAP geek stuff is to avoid conflating USPAP issues with licensing issues. Or lender issues, From my perspective, USPAP is merely one expression of the ongoing professional standards that have always been part of our profession, and from which it evolved. I'm trying to think in terms of the generic appraisal principles and concepts. Which existed prior to USPAP and which will continue to exist after USPAP is retired.
