The fact that minnows have more power is not permanent, it's just a temporary illusion, as long as the SP distribution remains the same. Once the experiment is over, (and at some point it will be over, you can't keep it going on forever, not without being counteracted by other whales) everything will be back to normal.

That's not necessarily true. There's some hope that the curve change that'll probably come with the next HF changes enough to make manual interference unnecessary.
