As I see it, a large set of computers all running a webserver over TLS can form a cryptographic global consensus (blockchain) for permissionless chat and other stuff. Sure, someone has to be running these serveds. But once they are ubiquitous enough, the government wouldn't be able to stop the chats by arresting / remocing any percentage of machines short of 90% or so.
What kind of traffic correlations would then be taking place? That someone is making requests with one of these servers? It's always hard to arrest a meaningful number of users once the network itself is resilient, uses a common protocol that resists deep inspection, and has no major points of failure.
