Sure, sure. But the idea that the process would somehow leave the fountain of youth intact runs contrary to the explicit desire of the Son'a to make the Ba'ku suffer.
We have little reason to believe that the planet needed to be rendered uninhabitable in the collection process. There might have been some truth to the Son'a needing the collector so that they would get the cure in time, but they could and would have lied about the collateral damage: a harmless collection process would probably have been perfectly possible, too, but that would have been contrary to Son'a interests.
Have you even seen the movie? It would've went smooth as butter until Picard stuck his nose in and pissed off Ru'afo.
Sure - as long as the definition of "smooth" includes all the Ba'ku dying horribly.
The holographic transport would never have arrived safely anywhere, that much is certain.
