But I think you can do psychotic shit like applying punishing sanctions to anywhere that permits an ungoverned connection. Or apply physical force (military).

I’m not saying we’re even remotely close to this, I’m just saying State-level coercive action is not unheard of if a problem is perceived to be significant enough to warrant it. Shit, it even only needs to be viewed as significant by a small subset of the governing body (see: Iran conflict, or current pushes for “child safety on the internet”). It just has to be “useful” to a certain body politic.
