I understand the reasons to be against it and if it weren't for enforced monopolies, I would be on that side. (let the market decide) But allowing those monopolies to be enforced, makes me think about long distance phone calls and Ma Bell (when it was whole), or the post office, without UPS or FedEX.
If you allow a monopoly and enforce it, then it needs to be regulated.
As to Allens do you want the government to decide what your looking at, they already can. Big business due it with marketing, bandwidth restrictions, protocol blocking (remember the Torrent lawsuits), etc. The government has that ability plus National Security letters. Kind of like choosing the lesser of two evils, is still choosing evil.
