To all the geek around here, could Bitcoin run entirely on a mesh network protocol rather than through the internet ? Would it be technically feasible or not ?

Cashu can work over mesh (see my project nutband).
I've wrote an article on "island" Lightning network deployments. Imagine a village with super unreliable internet connection. There could be professional nodes, using blockstream satellite to monitor for channel closures and providing channels (or a Cashu mint).
All this would work without internet (esp. if accounting unit is sats).
Bitcoin on-chain - probably best with Internet.
Bitcoin tx can be broadcasted over mesh networks, until you find a mesh node which relay it through internet.
We gonna talk about it with a demo during the B on Lille event, in September 👍
Yes but I mean the whole network blocks included, and a way to perform IBD or kind of semi trusted one.
Yep I can imagine this type of things but my question was more theoretical, can we imagine a way to make it work almost totally without internet except for initial node synching IBD (which could be semi trusted maybe with SPV like tech ?)
It comes down to how you want to solve the double spend problem. Bitcoin time chain is based on global consensus, so a global network of some sort. Lightning moves the double spend to cooperative peer to peer among two sides of the channel. No internet required in most cases. Ecash moves it to the mint(s). No internet required if you can reach the mint.
