Vidiot, the interesting thing about your suggestion is that those countries already pretty well exist. Some of the Islamic states, and even North Korea, look very much like the country you are describing. It doesn't take much of a stretch of the imagination to create the visual image of a country run along the lines of ideology.
One hurdle in the development of a JW state would be in the fact that they would very early in the piece need to have a police force (and very probably a military!). We'd soon see what side their bread is buttered on when that happened!
