if the gov has to physically send someone with guns to someones door to enforce a law, the economic feasibility of enforcing the law has already shifted massively away from the passive data scoop of a mass surveillance system. Why hasnt the gov won the war on drugs by just busting down every door?
I'm reasonably sure that it's enough to imprison a small number of dissidents to drastically reduce the number of people using surveillance countermeasures. Making examples of dissidents worked reasonably well for all kinds of oppressive governments.
