Going with the same analogy, sucking out industrial quantities of water causes existing wells to dry up because they are not deep enough. Then Nestle starts selling water to the village who now can't get water.

Nestle can pump out infinite amount of water from their many wells, much more than before, which is great, but Nestle also become the sole water supply and unregulated. Obviously, people cannot go without water, so they are at the whims of Nestle. Now, is this a good thing?
