You have enumerated a list of the worst services available to today's consumer. In none of those areas has there been any significant improvement in service level, cost, efficiency, or technology for many years (, though you could argue 'smart meters' will be a small step forward for electricity). Governments regularly use all of these utilities as revenue-raising 'businesses', which they consistently strip of any capital that could be used for infrastructure improvements.

In addition, some of the services have consistently proven unreliable, as they are run for the benefit of certain special interest groups at the expense of everyone else. Water is subsidized for farmers and golf courses, and this often causes everyone else to suffer droughts. Roads are often subsidized for truckers, which causes everyone else to pay higher gas taxes than they should, and suffer damaged road surfaces. Police departments are poorly regulated, and the policemen protect each other, resulting in the consistent and horrific violation of the rights of many people on a regular basis. Fire departments are run for the firemen, as can be seen from the fact that the number of paid firemen has been consistently increasing over the last 50 years, despite the increase of fire resistance of buildings, and the decrease of blazes.

All of these utilities also have some of the worst customer service available. On could argue that it is possible to get roads fixed through the city council, but this is the only one of the utilities mentioned which gives the consumer a modicum of recourse.

In short, if you are going to argue that ISPs should be a utility, please describe how it will be different from the existing ones, not how it will be the same.
