Purists always forget this point :) What is best for 99% of people.
And dumb Euro bureaucrats.

That's what can be achieved by encapsulation/containerization of apps: a la flatpak, snaps, docker or VMs...
I found my parents to install random crappy adware apps from official stores too. What protects their banking application is granular permissions, not root access.
