One thing to keep in mind is that one person's spare part may be another' srolen car or car parts. Especially in Europe, stealing parts is a thing. Some gangs won't steal entire cars, but only break in and take parts according to a "shopping list". Locking components to one another helps to make stolen parts useless and acts as a deterrent.

Yeah my dad and my mother both had their cars broken into and both of their steering wheels stolen. The door locks were surgically removed and nothing else was touched or ruined. They only removed those parts and went their way.

Then there should be a mechanism of being able to prove provenance of part and forcing the manufacturer to "re pair" components into another car without having to pay an absurd price.
