Well, I'm from Belgium, and based on the stuff I've observed up until now I would say that there simply aren't a lot of Scientologists here. The previous church was in a pretty insignificant building in an outskirt of Brussels, and the Dianetics center (now closed) was hardly ever open. I would say that there simply wasn't enough cash to be extorted.
Yes, I think that's likely the case with Rome, also. DM has to have the big glitzy buildings.
