It's not really true because Australia can't "enforce" 2+2=5, they can only punish Australians who say otherwise, which isn't meaningful enforcement. Suppose that Australia enacts a law that says: passwords must only be accessible to the government but no one else. How can Australia reliably enforce that? Regardless of what the government decrees, other people can exploit the same backdoors that the government uses to access passwords. At most, they can punish people who do that against their wishes, but only after the password has already been accessed and only if they find out. Governments aren't omniscient or omnipotent, what they can enforce is limited by natural laws. We have yet to find a way to overcome natural laws.
