Except “my Mac’s very secure and I can install whatever I want” is a complete fallacy. It isn’t secure - case in point Muse recently trawling through people’s messages. Or Mac cleaner like apps that trick users into installing them and giving liberal access.

I think if you don’t get the point of protecting a device against the user, you’ve not had to help un-tech savvy relatives get out of situations where dark or confusing UI practices have got themselves into a mess.

It would be a piece of cake to create a device that can be permanently downgraded for the un-tech savvy. It would be interesting to see how many customers would voluntarily choose that mode. My guess is that it would once and for all put Apple's security theater into the graveyard of stupid, annoying, and patronizing ideas where it in my opinion belongs.
