The politicians that want to identify everyone capitalize on organic desire for these proposals in the form of fear-mongering and "Think of the children!"
Citizens that want these laws are unthinking drones who don't want to raise their children, and instead want legislators to do it for them.
Politicians that want these laws are the people who, ideally, want to track your every move online for a multitude of reasons, not least of which are censoring speech and controlling narratives.
>organic desire for these proposals
Even if everything you said was true and there was a global conspiracy among the politicians, the tech crowd consistently denies and demeans these organic desires. We could cut the legs out from under these politicians if we listened to these people's concerns, considered actual solutions like OP did at the top of this thread, and turned these people into allies against those politicians. But instead we deny the actual desire to protect children and accuse them of either having ulterior motives or being sheep, turning them into permanent enemies thereby empowering those (hypothetically) conspiratorial politicians.
