^ Let's try a metaphor ... in my home state we get occasional forest fires, people in the path (wind blown path) will sometimes be required, by law, to evacuate. It not that the government want to "take their land," it's because if they stay, the resident might be harmed.
What I took away from the movie was that the Sona would have simply collected the particles and the Baku be damned. But the Sona approached the Federation first to get their permission to collect the particles, the planet (in the eyes of the Sona) was in Federation territory, and the Sona didn't particularly want problems with the Federation. When the Federation discovered that there were colonists on the planet, they would not allow the Sona to proceed, knowing that the people on the surface would be killed in the process.
Remember, no one want to take the Baku's land, the Federation wanted to protect the Baku from "
the forest fire."
According the Admiral, the Federation council sign off on all of this, why the Baku weren't openly approached and simply moved I don't know, that how I personally would have done it.
Apparently, neither the Federation nor the Sona really cared if the Baku thought the planet was theirs, but again no one wanted the planet, to the Federation it was irreverent, they wanted the rings only, once the colonists were off, the planet was disposable.
Most probably, the Baku would have continued to benefit from the effects of the rings, even after they were relocated, just like hundreds of billions of others in the Federation would have benefited from the effects of the rings.
Assuming of course that the medical effects were real
after collection, none of the Baku would have been "condemned to death," if the assembled Baku wish to continue to live in a isolated valley some where, the Federation was "a thousand worlds and moving out," there was likely a unoccupied valley
somewhere.
The Admiral also said that the effects of the removal of the rings would effect the planet's surface for "decades," suggesting that the effects were not permanent. Were they so inclined, the Baku could have re-establish their settlement, in the same valley, if they wished. Because no one (again) wanted the planet. The particles would have
still been available to them.
They just wouldn't have had exclusive access anymore.
