the internet is just the means of transferring data, it is totally incidental. if the internet is one day replaced by a better mode of data transfer, bitcoin transaction data will be sent on that instead. figuring out solutions to internet shutdowns only makes the network more robust.
In my honest opinion, the whole point of Bitcoin is to be a decentralized payment network on
Internet.You making it "without internet" completely ruin the fundamentals of the project itself.
Maybe make your own cryptocurrency which works on satellite?
