You make a lot of good and important points. I don't fully agree with your post.

Phone companies rely on infrastructure built by the government. If we had government internet infrastructure and then used store-bought equipment to access it, as we used to with dial-up, then we'd be back where we were.

I do not see how the government can reduce barriers to entry sufficiently to enable new firms to enter and compete unless it provides the infrastructure and rents it out competitively.

Once that has been done, then consumers would have a real set choices, and abusive firms would simply be abandoned. Until it is done, or until technology goes completely wireless, there will be monopolistic characteristics that enable abuse (and result in demands for government prevention of that abuse).
