> Normal people either don't know the dangers present

But what are the dangers? I mean concretely, in a way that can affect their day to day life, with significant probabilities.

HN is a tech forum, people here are very aware the tech risks. But talk to anyone in a given field and they will find a way to scare you. Don't go out in the sun without SPF50 gear or you will get cancer, your house electrical system is a fire hazard because you don't have the latest breakers, buy a gun, don't buy a gun, have this and that survival equipment, learn self defense, never talk to the cops, don't leave your drink unattended,...

At some point, people just want to stop worrying and do their things. And guess what, most people are fine! In fact considering how many things can turn bad, normal people are rather good at avoiding the worst despite an apparently carefree attitude. Meaning they are not so bad at evaluating risks, and that society has pretty good guardrails.

So cut normal people some slack unless they are in immediate danger (for example if they are in the process of responding to fishing), uploading their picture to Yoti is not that. They have other worries in their own field.

Inform them, but don't press it, and if you are in the field, your job is to help normal people be carefree, not cause more anxiety, they have more than enough already.

One of the dangers is in the ability to cross-nationally attack someone. As digital infrastructure continues to encompass more and more facets of necessary interactions with the government and governments force more and more points of interaction someone from a foreign nation could destroy the life of someone who is interfering with their aims. Say someone has published an article that reveals the terrible behaviour of a given company. Someone hired by the company can use a variety of data points to not only track down who that person is, but where they live and even which room in their house they spend the most time in. With that kind of information it would be easy to financially, reputationally, or mortally wound someone. With the worryingly swift growth rate of corruption this could apply at any level for any reason. And unlike for example the difficulty of getting into a car crash or robbing a cash register, digital infrastructure makes all of this remarkably easy and for some parts even free. With modern LLM agents it could be entirely automated so that no human is ever involved, and because there's so few current guardrails and such a vehement protestation against any being implemented the agent could wipe it's connection to it's handler so that nobody ever faces any consequences.

The thing is, this kind of stuff already happens all the time. The number of spam calls people suffer through are a direct result of companies digging through the contacts list after being granted that permission (though often without being granted that permission), then selling that data to brokers. Data breaches that wipe people's credit or force a credit freeze because they bought something ten years ago are another common one. Or think about package stalking, where people get access to someone's purchase history and the tracking number to a purchase so that they can steal it in transit or once it arrives. There's a number of beatings and murders that have happened because of police officers being able to access surveillance tools to track former romantic partners or spouses. All of these are different parts of the lack of privacy, and they're all getting worse because the tools that are used to surveil are becoming more widespread and more accessible.

Privacy is a protection against the intelligent attacks of other humans. It is not a frill that can be taken away without ridiculous and trailing harm.
