I like the concept of regional rules, and the fact that they keep changing (Gold Saucer has Chaos for us today, which kind of sucks, but hey). It adds a bit of diversity, chaos and, for me at least, fun in matches that would otherwise be stale and just the same thing over and over and over and..

With that said, I wouldn't be opposed to a small area somewhere which had no regional rules for those that don't want them.
