The Information Superhighway is just a metaphor that requires no actual concrete.
Your Superhighway metaphor-metaphor is getting further into the ether, without adding substance (unless you can make your statement about concrete more concrete).
Sometimes I wish there was an 'easy button' to figure out the context of comments.
In short, every aspect of how we interact with roads and cars is pervasively shaped by the rivalrous nature of roads, and their excludability profoundly affects many social institutions. Only in the most rural areas are roads even approximately non-excludable or non-rival.
Will some aspects of life move from the physical to the virtual? Sure; they have and they will continue to some extent. However, there is a limit. Cyberspace cannot exist without physical space. If you want to ascend into some kind of purely spiritual existence, you need to look elsewhere than technology.
Market failures are a real thing, and you need some sort of institution to address them. The internet does nothing to change this, except that it makes it possible to create more discriminating policies that are more efficient (in theory).
You are saying that if a good isn't being provided, it's a failure. But who told you the market would give you everything you want for free? Who stops you from raising money for your pet project?
