While I think pipes owned by the people and leased to private ISPs is a very interesting solution, I don't think it would fly with the zero-government crowd.
what I don't understand about these people is that they must recognise that comcast essentially functions the same way the dreaded government does. They are just as large, they are just as organised and powerful. But in contrast to the government there is not even a democratic check and balance, and an explicit profit motive.
I would assume someone who likes the 'market' part in 'free market' recognises that a single giant corporate entity is not very market like at all
