Well, it works for China, so I don't see why it wouldn't elsewhere.

As a techie, I'd like to believe that there are limits to what can be passed as law, but the history shows that it is not so. Just because something is technically impossible doesn't mean it can't be required by law, with all the consequences for not complying. It's uterly futile to go against the people in power with technology or even science alone. The best you can hope for is for you and me, personally, avoiding problems. For a time.
