Do you have a citation for the cases where Apple has successfully argued used this in court against some other party who was pirating OSX?

It's only "nifty" until it's put to the test and fails in court. It's "effective" as a way to protect software only in the minds of some Apple engineers; but a judge might not see it that way. There's no precedent to assure anyone that it would work. If there were, I suspect we'd see it in widespread use. Or maybe Apple has tried to patent it?

Perhaps the DMCA exists because "nifty" gimmicks like this one cannot be relied on?

Nice try.
