The way I see it is, I can't spend them anyways, so essentially they are worthless to the whole community, if by some miracle, this process allows theft of the 1.75 to 1.9 BTC in this wallet, then overall it benefits the BTC community by having more BTC available for use on the network overall.
This is wrong thinking, I think.
Those BTC (if Dave was a thief, which he is not) would not benefit the community, just Dave.
Also: Consider that if those BTC are inaccessible, then all other BTC are worth slightly more.
