So, just to be clear: this isn't a blanket belief I have about technology. The modern Internet, however, appears to me to have developed largely in response to consumer demand, first for email, then for web pages with pretty pictures, then for secure web pages, then person-to-person audio, then small-scale video, then large-scale video. At each interval, some random company introduced software demonstrating one of those features, and it caught on, and the Internet was built up in response to it.
An ISDN BRI was zippy fast in 1997. I liked my ISDN! And if it weren't for Youtube, I might still like my ISDN.
If the Internet were a regulated utility, we'd have to petition for the local Internet authority to roll out something faster than 128kb/s. But of course, I didn't petition to get my DSL line: I just switched ISPs to one who'd provide it.
Lord only knows what Google would have had to do to get Youtube connected to the counterfactual regulated Internet.
Like I said elsewhere, I think regulated utilities work reasonably well when there's just one figure of merit (usually: price). I think the approach falls apart when the number of variables increases.
