I totally get that Apple is constantly under seige from scammers, knockoffs, etc. Not my problem.
Further, setting up official spares channel would likely resolve 90% of fraud by fullfilling a definite need. No diff than acceptible streaming moots most demand for pirating.
Lastly, I'm fine with self repair requiring an official factory reset, or whatever, for stuff dependent on the secure enclave. Like rebinding FaceID to a new camera/display assembly. A fair tradeoff between security and convenience. So I can repair my phone now, suffer with entering PIN, and then make a quick stop at a Genius Bar later, at my leisure, to reenable FaceID. With so many third parties trying to pwn Apple gear, I totally grok this precaution.
