I think that the medium shapes the resulting political characteristics of the system, yes the centralized network, where every user is easily traceable thus readily policed and censored, ends up creating totalitarianism, given how human nature works... So we need to design a system that isn't easily traced, as an inherent property of how it operates, so that it's not possible for those who want to exert power over others, to do so. Just as an example, using a radio/satellite data broadcasting architecture, where the receiver is untraceable, means that the government can no longer round up people for reading "forbidden" things anymore. That allows us to have a new darknet to replace Tor that's far more difficult for the government to police. Again as an example, the content request can be transmitted anonymously using HF radio or LoRaWAN, being only a few bytes, and has no sender address. And the response can come down via satellite, broadcast to everyone, who also ends up storing it locally on their computer. That way we can reduce the number of retransmissions required. We already have a usable worldwide satellite data broadcasting network, you can see a list of recent transmissions at https://blocksat.info https://blocksat.info. It's certainly enough bandwidth to support a text based darknet, which works in a similar way to how Teletext did, but with caching of content on your local hard disk. Which you can browse freely like the Internet.
