Bureaucracy like that is always a short term obstacle. US building codes are not much of a quality or technical challenge though if you consider that Tokyo has typhoons and earthquakes and is planning a 350m skyscraper with CLT. I'd say anything suitable for that, ought to be acceptable for construction in most of the US. Compared to the damage that hurricanes do in the US to flimsy plywood buildings, it will probably more than be able to compete with that. Building standards are perhaps slow to change but not necessarily very advanced in the US. But you are right that this type of change is slow to implement.
