No way. Once you have a public ISP like that, it's one "minor reform" away from running parts of its operation at a loss, for the "public good". And before you know it, it's controlling the market, distorting prices, and holding back innovation.
Yes, privatization of utilities has been a very successful policy and was implemented across the world over the last few decades.
The case for internet service being private is very strong. Do you really think a government bureaucracy would have developed the internet to its current state if they had taken it over in the mid 90s? Competition and the profit motive is what has gotten us this far.
the government actually privatized what was at the time a public infrastructure connecting govt agencies and universities in the early 90s.
i agree with you that the internet would not be what it is today if it had remained in govt hands
i also think that if it had evolved soley from the private sector, the kind of balkanization and complicated service contracts that people are concerned about today would have been baked in from the start.
