I have definitely fallen victim to that one myself, and have pushed that argument when considering Apple's walled garden in iOS, and how much that has assisted me personally in not having to provide tech support for members of my family.
Unfortunately, between these arguments, and the continued push of individual/consumer responsibility and "vote with your wallet", the vast majority of people do not focus their attention on how technology platforms work, instead focusing their interest and energy in other areas, and will "vote with their wallet" for whatever is the simplest solution at the time.
First order effects are generally not considered when it's not something you care that much about. Second and third order effects are definitely not in mind.
The only people who care enough to give up all privacy on the internet in exchange are deeply misunderstanding what normal people care about. Uncle bob would much rather the meme he made about weed not trace back to him or get to his employer with his fingerprint.
whether some video was filmed in xy doesn't matter unless you're in some sort of political crisis. Bob isn't. You're using a fictional bob to represent your own desires and present them as 'everyman issues'.
Bob doesn't care, and if he did he'd already use authentication. This is your problem, not bob's, but you're using a fake bob as some kind of 'personal shield' for an opinion leaning towards sacrificing freedom and privacy for very little in return.
What real bob wants most is probably less of you interfering in what he can see and read. He's not your kid and your intrusion on his freedom to read and speak are aggression against him.
Edit: don't get me wrong, _not_ doing that for children is evil. But, the results thus far do speak for themselves... And uncle Bob will not take being sent back to middle school all that well.
You have this idea that society is a monolith you can keep people in and out of based on the results of an algorthm, and that's only true for the most authoritarian and oppressive regimes.
That's the world you're trying to create. Social Credit scores as maintained by facebook, etc.
It's truly repulsive.
Almost everyone get's swimming lessons and tests. And yet, and this might really blow your mind, you can still actually go swimming without actually having had passed the test. No SWAT team will barge down your door and take you away if you go swimming.
Then whats the purpose of the test? Tests are scores used to determine something. You're talking about forcing people to take a test to do what, exactly? Or is it just to indoctrinate them with whatever the test-maker (because it will change every election) comes up with? A thing you must study for but with no reprecussions? Ya right.
Once you create a certification for it, it will become a private passport for access to goods or services, or it will be meaningless. In both cases its either a waste or evil.
I'm not sure why you keep going down this dark path which I didn't even touch on remotely. You just completely imagine it.
