The suggestion from OP whereby the seller of a used phone logs in and "unpairs" the parts could avoid this, unless a robber forces you to do it under duress.
Isn't that possible with the full iPhone atm?
it's resulted in a few deaths in chicago at least
They wouldn’t live to tell the tale

and before you dismiss it given the time of day or one off, armed robberies for cell phones are way up in chicago and they are occurring in broad daylight . the crime that keeps getting covered and that I know someone who this happened to is, 1 -2 people walking on the street, a car pulls up with 4 people . they all get out and have guns and force you to give up your phone and passcode. Armed Robberies are way up 44% 7978 cases and they are all for iPhones and passcodes . people are getting pistol whipped when they don't cooperate and increasingly even when they do.

Overall I think it's pretty safe to pull out your smartphone in public these days, which was not the case years ago.
Stolen phone? The phone is still activated, part can't pair with new phone. Not perfect, but at least somewhat less anti-consumer.
By restricting the reuse of parts, when you crack the screen of your old phone, you are faced with a $500 repair bill, and decide to just pay your phone company $50/month for a new contract that comes with a new phone.
It's almost always the same play book:
- moves to some US address nearby
- turns off for days
- shows up in Shenzhen or Guangzhou
Usually from there are a few attempts to phish the owner with fake iCloud alerts (and sometimes outright threats) before they strip it for parts.
To be clear it's not like the phone theft itself is part of some concerted effort by Chinese actors: there are only so many places where the tools and skills to strip down, repackage, and resell something as specific as an iPhone speaker unit are so common
No threats though... I assume they just parted it out.
