It actually points to the solution. Surveillance is only convenient when it works one way. As soon as you add counter surveillance to the mix it becomes more tricky. Now you can watch but others will be watching you watch others. Add some laws to the mix and now you actually have to stick to them because others will watch you break the law otherwise. Fine if you control everybody else (i.e. you are a dictator) but less so if those others are your political opponents, other countries, or anyone who might not be under your influence that can call you out on what you are doing; especially if there are consequences to you breaking the law.
