I don't blame building codes, but I do blame governments for just trying to derive their own building codes in an NIH fashion. Engineering best-practices (which is what building codes are) advance in global lock-step in every other industry, because—once it's proven that approach X fails less than approach Y under conditions Z—X should be used instead of Y for all Zs, no matter what country you find the Z in.

Regional considerations for things like earthquake proofing, density planning, etc. can be built into a single overarching engineering standard, just like considerations for different company shapes with different needs are built into a single larger tax code. There's nothing having many different local algorithms can optimize, that wouldn't be even more optimal as many different local parameter values to a single parameterized algorithm.
