According to whom? The Internet is delivered to homes on top of existing regulated utilities, that are quite essential to our survival. But I can use the Internet anywhere with a sufficient enough population density if I pay for a wireless data plan. Because the true value of the Internet is global availability of information, access to that information doesn't need to be tied to a physical address in the same way a life-saving device like a telephone does. Really energy and sanitation is what we should be thinking of. They're truly necessary utilities.
