I disagree, think of Friendster, or even Myspace...the social networking crowd can be fickle, if facebook screws up that leaves a market opening for a competitor (ie. Google, Microsoft etc)

While this may be the opinion of the small group of libertarians who did this study, I know for a fact that many proponents of the Austrian School of Economics would not agree. The Austrian school forms a basis for libertarian philosophy. There are several Austrians who argue against IP altogether, so I see this as a misrepresentation of the platform. Look up Stephan Kinsella for instance.

The "singularity muppets" as you call them, are more concerned with informational technology, and the implications...as opposed to physical technology, which obviously isn't progressing as quickly. Advanced AI doesn't require a flying car.

It's not that, it's just the cable industry is so inefficient and in bed with government institutions that it has no incentive to innovate quite simply. If the market were to "free up" a bit, we might see some competition pushing for quality.
