MacOS does more than just give you a warning when you're opening a program not vetted by them -- it prevents you from opening it, so that's not really a good example of education, and is in fact an example of lockdown.

I'm not arguing that anything get any more locked down than it already is, so your points (while possibly valid in a bigger discussion) don't make a lot of sense here in this discussion about a hypothetical "unlock phone" setting.
