Presumably, you can pay someone else to do it. And as long as the thing being worked on follows some reasonably open standards, there is a competitive market for those workers, so you can pick and choose.
That's the thing. the public actually believes that the hood welded shut is a good thing because they don't get these things, and immediately forgets that their "mechanic" won't be able to repair their stuff anymore.
Their mechanic wouldn't be able to repair an apple car with all the unlocked hoods in the world anyways. Take teslas as an example. Short of routine maintenance on suspension parts and brakes, regular mechanics aren't able to do much.
