It ultimately can't be, though. All it takes is for those governments to push for international enforcement of their laws for their own citizens (which already has precedent) allowing foreign subpoenas for IPs, or limit VPN use to require corporate/private licensure, or any number of other avenues of legal or technical attack, at least one of which is likely viable and already known to the Chinese as a contingency.

People who chuckle at "hurhur dumb legislators" ought to be scared shitless of the forest they're missing for the trees - the precedent that's being set as an impetus for further action in the future.

"But we still can now" is just that "first they came for the X" recitation all over again. Hyuk it up now, and by the time your avenue gets shut off, everyone else will have already been cowed into submission. It's the basic freedoms that are important to defend, not the loopholes that defer your fate.
