I agree with your ethos, but I don't share your optimism. If the state wants to enforce networking firewalls along national boundaries, no technological solution will save us in general. As a resourceful techie with the right know-how you may be able to sneak your packets through, just like people in Cuba receive a literal packet of data via sneakernet, but if the state doesn't want widespread meshnets circumventing their firewall, they will imprison you for emitting pirate radio signals, they will penalize any electronics manufacturer that makes non-compliant hardware, and rest assured that companies will go right along. Liberty requires more than technical solutions.
I'm saying this as someone who once wrote a decentralized P2P mesh for instant messaging[1]. I was inspired by the HK protests going on ~2014 after hearing that they were using Bluetooth chat apps. Luckily Matrix, Telegram, Signal, etc. mostly solved the problem. Still, I don't think any amount of mesh networking would turn back the tide of Hong Kong now.
