TREC Inspector Insight mentions InterNACHI indirectly and TPREIA directly.

Nick …

Very interesting concept.

Real estate license holders have a fiduciary obligation to serve the best interest of the party they represent.Inspectors have a contractual obligation to do the same. This aligns both the broker/agent and the **inspector on the same team – if they both represent the same party. There is no inherent conflict of interest between these two professionals. However, a broker/agent may represent the other party to atransaction and would be required to protect that party’s interest. *If the home inspector ‘s observationsand opinions are offered in a straight forward manner without unsupported “findings”, all parties are likely to respect the report’s contents – regardless of which party the report is prepared for*

In an ideal world you would be correct except that is not the real world and sometimes money wins over ethics.
