Ok. Cars can be used to ram raid buildings, to try to rip atm from walls. Used to package, carry and execute bombings. Should we ban all vehicles? Or better yet, guns. They can be used, and are used over and over again to attack and terrorise innocent people out at the shops or going to school. Should all guns be banned? The internet can be used to learn how to make bombs and other weapons for the use of terror. That doesn’t even need to be anything special either, simple google searches will get you there. Should we ban the internet. I’m sure there are clearnet sites that post things that shouldn’t be posted its not just on the darknet.
I do agree with your last point though. You can have full security or you can have full privacy but you can’t have both. I think the main argument is because you value security more whilst myself and others value privacy more. Both, in my view are fair and valid.
