I'd rather have my Apple devices which have some economic value to be findable using Find My, which can't function with a physical "hard" off switch.
Why not? I mean obviously they wouldn't be findable if they were off, but that's a feature. Apple could add a physical switch and leave everything else the same. Your devices would function as they do now in "On" mode, but you'd also be able to turn the off properly. Isn't that better?
