> the OS a provides a function to “unpair” a part With your idea, if my phone gets damaged to a point I can't access that function anymore, all of its parts are non-reusable and complete e-waste. IMO a better and less complicated solution would be to blacklist the serial numbers when a phone is reported stolen, and phones can check serial numbers against a server (if offline just assume the parts are fine for now). Parts should be considered innocent until proven guilty, not the other way around. There's probably ways to break this system such as blacklisting the servers from your DNS and never connecting to any network other than your home, but it makes the phone much less practical to use and it only takes one slip-up for the phone to brick itself
