Or, put simply: how much US oil comes from fracking? Not a small number - the aforementioned 65%. Source for this data: the U.S. government.

Remember, these aren't small amounts of water either. I live in California, where we have drought conditions. How much water do you think a typical well uses? "Up to 9.6 million gallons of water (!!!!) per well." For just one well!

That whole sentence is worth quoting in full:
Oil and natural gas fracking, on average, uses more than 28 times the water it did 15 years ago, gulping up to 9.6 million gallons of water per well and putting farming and drinking sources at risk in arid states, especially during drought.
So, here's the thing. The "cost" of that water in the market is just the cost in dollars. But to Americans, and future generations? It's much higher. You can throw a stone at a US map and hit a state that's experiencing drought conditions right now (and that well water is permanently off limits for drinking).
If we can slash the real cost - the externality cost - by just buying it from elsewhere, we should. And we do. And that's the right choice, despite what NASDAQ thinks.
