The function of the anti-theft mechanism is, at its most basic level, to assert the concept of "rightful owner".
Subverting these mechanisms provides a way to prevent the system from making this assertion.
Likewise, the alleged "anti-repair" mechanism for TouchID sensors and TouchBar relate directly to protecting the system's ability to distinguish between the "rightful owner" and a thief.
"Do what I want with the machine I own" is functionally indistinguishable from "increase the resale value of the machine I stole".
