The scene was filmed, but not used. Toward the end of the movie Quark (of all people) shows up and anounces that he is indeed going to open a spa somewhere on the planet, so people can come for the health benefits of the rings. Picard tell him that he (the guy who make all important decisions in the Federation) will not allow any spas on the planet. Non-canon of course, never made he final cut. Why would any facilities have to be "low tech?" Having modern 24th century mega-cities on the planet shouldn't interfere with the incoming radiation. Again why? However, the ring planet is in fact Federation property. Also there is no indication in the movie that the Baku ever formed themselves into a state. Given that they are living on someone else's planet, how could they? It was the Romulan's, then the Klingon's, then the Federation's. Never was it the Baku's.
