This cute video points out how silly it is to pay for "stuff you can get for free," but remember that tap water -- although cheaper than bottled water -- needs to have a price if (1) we're going to maintain water systems and (2) want to ration its use when it is scarce.
Indeed, this issue has been around for awhile. Just watch this campy but still-relevant take on "water privatization: exploitation or business?" from this 1958 episode of "Leave it to Beaver"
