How do we know that those repetitions are not needed to accelerate (by parallel processing) some important process which, with a single expression, would otherwise be too slow to survive?
You absolutely do NOT want them to be expressed. In fact, your genome tries really hard to suppress them - all they do is replicating themselves. That's the reason so much of your genome consists of them.
Dependency on statistical properties is doubtful - organisms have more than 100x natural variance in genome sizes within fairly closely related species (just look at plants) without much outward difference. Even in animals, some species have a small and compact genomes (pufferfish) without much junk.
It is easier to write an incorrect program than understand a correct one.
