Technology has evolved and users don't control their stuff any more. All kinds of things like parts serialization, cryptographic attestation, etc. are finally getting to the point where it's impossible to bypass the controls.
As those solutions get polished and become more accessible, we'll see a rapid increase in products and services where users never truly have control over them.
Even worse, I'd say that between businesses and people that want to keep their kids safe, the majority of people will opt-in to boot-locked PCs if they're marketed for safety.
Give it a bit and I bet Microsoft will start offering some kind of secure or safety mode for Windows PCs. The TPM requirement on Windows 11 must have some long term goal associated with it, and perfectly locked down devices doing attestation is likely part of their identity play. Whether it's attesting for or against the user is another question.
"An entire generation learning to obey big brother for face the consequences sounds like a good thing, the youth need to learn their place. I support this" your unstated counterargument.
