Earlier quoted context omitted.
For a lot of things we don’t opt for the cheapest solutions that also lack redundancy for a lot of things. Why not for the “information highway”? Most efficient = cheaper. A lot of times cheaper sacrifices quality, and sometimes safety.
It's not even that. It's that "centralization is more efficient" is a big fat lie. If you look at the "centralized systems" they're... not actually technologically centralized, they're really just a monopolist that internally implements a distributed system. How do you think Google or Cloudflare actually work? One big server in San Francisco that runs the whole world, or lots of servers distributed all over?
Why do you think they're a monopoly in the first place? Obviously because they were more efficient than the competition and network effects took care of the rest. Having to make choices is a cost for the consumer - IOW consumers are lazy - so winners have staying power, too. It's a perfect storm for a winner-takes-all centralization since a good centralized service is the most efficient utility-wise ('I know I'm getting what I need') and decision-cost-wise ('I don't need to search for alternatives') for consumers until it switches to rent seeking, which is where the anti-monopoly laws should kick in.
