I'm well aware of this process and support it. Countries are welcome to make any deals they'd like. They're presumably intelligent, independent entities making decisions in their own best interest.
I recognize their right and potential desire to do it, but I think the likely economic responses and ensuing global downturn isn't worth the eventual possible payoff for them
As an example of an actual unpopular opinion I have, I think it's good that countries sell Nestle their water rights and then buy water back from them, if it results in a large enough economic impact for their nation.
If it means jobs at Nestle, income for the government from a large corporation that otherwise wouldn't exist in a developing nation, and increased standard of living nationwide? Yes, absolutely.
