governments should restrict the Internet to what say a North Korea regime has, so it can only be used in a restricted fashion, where only those certified by some credited establishment (so they are easily traced) could possibily create cyber attacks due to limited access for a gen public.

This in my opinion, would cost the tax payer far less money due to the pentional income loss a cyber attack would bring to the US economy, and of course, still provide access to a vast few (in terms of a multipke hundred thousand, non-percentage of the whole population), so some checks and balances are in place
