I'm pretty sure that the ISP sector is not constrained in any way by a natural monopoly. Take a look at the Internet in Romania wikipedia article[0]. In my view telecom companies have grown to disproportionate sizes, almost everywhere in the world, and this has given them enough power to buy the lawmakers. A lot of legislation has been passed to protect them, state laws, national laws and even international laws. So no, I think that the telecom sector has been intervened enough since its creation, what the consumer needs is to completely deregulate it, and to let the free market work its magic.
