Wow, 234 pages! :)
Long read, but thanks for posting that. I downloaded it to study in more detail, but a couple of things unexpected to me that stand out in a quick perusal:
Most Southern states, which you generally think of as "free" ended up getting pretty crummy scores overall regarding regulatory issues.
Wyoming didn't fare well in many categories. Surprising based on how well the Dakotas, Montana, and Idaho did. I've always grouped Wyoming in with those states, and have thought of it near the top in that group.
