So you suggest that we give up all privacy (including the privacy of all our online passwords), and lose access to every page that a government censor might take issue to, just to prevent the hypothetical problem of the government over-blocking pages that it doesn't strictly need to? Actually I think that over-blocking would be good, as it would encourage more people to use Tor and VPNs, it would encourage more negative public opinion against the government spies/censors, and it would act as a form of economic sanctions against the regime because their citizens would get less value from the internet than they would without the over-blocking.
