I disagree with this. I have never enabled Find My because for privacy reasons I don't want my location being transmitted to Apple.
What would be better is some means of opting out of Find My being able to ever be enabled on my device.
If I ever sold my device I'd have to communicate that to the buyer, and I may lose some resale value, but that's a compromise I'd be willing to make.
I am not sure I see the feature being very useful. If you have lost your laptop without Find My enabled, and someone else gained possession of the laptop and wanted to activate Find My but couldn't because of this feature, you would still almost certainly not be able to recover the laptop. So what does the feature do?
Take this story, for example. If the laptop hadn't been bricked, it seems unlikely that it would have found its way back to OP.

How would that work? A fuse inside the device? Seems like it would make the device vulnerable to an electrical hack.
Why would Apple develop such a feature anyway? I bet fewer than 1% of users would use it.
