I'd like to hear more about what you know of EU identity theft. Specifically as I am from Belgium, my bank is protected with 2FA and my eID identity card should protect me from criminals creating contracts on my name. While probably not bulletproof, I can't really name recent common identity theft troubles. Most damage seems to happen by providing the android/apple/steam/... stores direct access to your bank account or identity, so AFAIK the main advice here is: don't.
Also: What is your alternative? I hate my own post above, but can't really think of anything better.
Without severe expansion of data privacy laws universally, most of my alternatives fall short. I can tell somebody to use 2FA and to be selective about their data, but what good does that do when companies are barely complying with GDPR as is? Our solutions are mostly to know bad things will happen and to have it affect as little as possible so you only have to change one password/account. Bleak. It's disappointing in a way, we could do so much better; substantially improved data privacy laws and mandatory e2e encryption would be great first steps, but they would enrage the very same corporations (like HP) that pull off this nonsensical garbage that puts us all at jeopardy. They keep pushing all these tracking services updates to those to restrict use and enforce sales, we can't handle this by just telling people to update less because eventually other companies will start adopting those policies if it results in increased ad revenue.
I also don't think your post is to be hated, it is not bad and is actually important in getting people on board with the idea of mass reinvention of digital services. We can't get there until we all accept that digital life currently is just far too invasive and we need better regulation before we can even start to work on personal advice. Such personal advice from Telekom[1] as an example, most of it sounds good but doesn't actually work in reality due to how weak our data privacy laws are.
