I like to visualize technology that might be possible in the future, like some quantum scalar-wave communication tech that is not limited to any geographical distance and also not time-delayed like ordinary radio tech. Studying the EPR experiment, quantum entanglement and surrounding research and information strongly suggest, at least to me, that it is very much possible. It would allow for a truly peer-to-peer new "internet", and with open source community-driven hardware as well as software, we would be on the next step towards actual information freedom.
Just babbling on here haha...
You are probably looking into the direction of redundancy. Introducing an additional novel method of communication wouldn't make it more "redundant". Reason being, if people needs to get a completely new tech just to use Bitcoin, then you are raising the barrier of entry. It would only exist if the government which the users are in supports Bitcoin. Using an infrastructure that doesn't already piggyback on the country's core infrastructure is counterintuitive.
