In the dissent, they call out that what Nixon did wouldn't have been prosecutable under this interpretation.

If you can't enter private comms into evidence, all a president need do is privately communicate the disappearance of someone, domestic or foreign, and that evidence would be barred from any possible court cases.

Of course, you could still impeach, but no criminal prosecution could occur. If you're 35, at worst (legally) you'd lose out on your remaining term.

The implications of this ruling are absurd, and rife for abuse, should one decide to go rouge.
