Vulcan is still a Federation planet, in Federation space. That argument is irrelevant, as it had been established that Federation policy was to honor the wishes of any de-facto governing council of any world that could prove they had a proprietary claim. If the Federation cannot tell the Vulcans(their own history says they are unlikely to be native to Vulcan; TOS episode Return to Tomorrow makes this postulation, by Spock himself) they have to vacate their world because reasons, they can't say it to the Ba'ku either.
The health properties of the particles is entirely dependent on their availability. Destroy the rings/planet to collect them, you have a finite quantity, with no way of replenishing them. Once they run out, they're gone for good. Better to keep the planet around, rings and all, to make certain the particles stick around for a long, long while.
See above and realize - if the idea is to keep the planet/rings intact, the Federation won't allow the Son'a or anyone else to build another collector.
There is much we don't see in Insurrection; however, that has no bearing on whether such unseen events, even though they're non-canon, ever actually occurred. It's likely that Sojef, Anij, and/or several other of the Ba'ku elders that had been there from the beginning were willing to travel to Earth to petition the Federation council in person to leave them alone. Allowing the use the far side of the planet as a spa, so long as they stay on the far side, is easily something the Ba'ku might be willing to go for. Essentially "Leave us alone over here, and you can have anyone you want go over there to take advantage of this place. Just make certain to leave us alone over here."
You keep seeming to forget, the Ba'ku aren't backward, or undeveloped; their Luddites. They have access to 24th century equivalent technology. They just don't want to use it. I for one can see the appeal of living a simpler life. But I also see the appeal of making sure that I don't throw away my ability to defend it where and when necessary. This series of events did much to make the Ba'ku aware of just that necessity, and with their elders being first-hand familiar with the ability to take advantage of it, they're the ones most likely to make certain everyone else knows.
