Well as much as I am a advocate for converting to a cooperative economy, I do understand that logic. Our corporate capitalism today relies heavily on monopoly like power especially with things like intellectual property and businesses like ISPs. If Comcast was forced to provide commodity access to its network as well as interconnects with other line providers, then the monopoly like power Comcast has over internet access would be dramatically reduced. More competition would enter the market and theoretically lower prices. Or if intellectual property law was significantly weakened then we would see more competition as well.
I think you might have misunderstood my comment. I'm arguing that more competition may be good for consumers, it's not doing any favours to the environment. Cheaper stuff means people consume more, more consumption means more environmental damage. Any effort to restructure our society and economies that doesn't put environmental impact first, is the wrong change.
