Well, it doesn't. Absolutely none of the systems people are putting into place, or suggesting putting into place, are actually zero trust. The ones that claim to be are "somewhat lower trust if you don't think hard about how to exploit them". Yes, we know in theory how to do zero trust. The reality of these mandates is that people can easily get de-anonymized to all kinds of actors who should't be able to identify them.

It's also a "solution" to a massively exaggerated problem, one that's not in any way specific to any given age group. But that's unrelated to the fact that nobody is, in practice, doing or planning to do anything privacy-preserving.
