"...Southern Idaho (i.e., most of the frickin' state, thankyewverymuch) most assuredly has a water problem, unless you use non-Libertarian methods (public water projects) to impound water..."

Then you're not a Libertarian, because every Libertarian I've run across says that eminent domain (required for water projects) is EE-VIL.
