When the private key is gone, the coins are gone.
Might be forgetting a brain-wallet, might be forgetting the password or losing the keys to the encrypted drive the keys are in, or it could be as simple as losing or destroying the physical media the keys are on.
We can quibble about the precise technical details of how DPR specifically might have those coins secured, but it's mostly moot at this point; that address likely won't be changed any time soon.
Surely removing 1% of the current circulation must have a few effects.
