Another thing about utilities: water or electricity are fungible goods, easily measured. Search is rather trickier to decide what a good outcome is, and the thought of paying for politicians and administrators to debate search rank orders for eternity seems a terrible use of money.
Finally, things like water supply have been around for tens of thousands of years. Thinking search hasn't done so much in the last 10 maybe be a little short term! Thinking it will be around in the long term at all, and thus worth converting may also be a little short term.
