If nothing else, at least with this kind of "news" we refute claims that some BTC is lost because it hasn't moved in xx years.
I actually keep wondering about these "lost" coins. Do they account for only coins supposedly actually lost like in a steaming pile of garbage, or in burn addresses, or do they also consider dormant ones?
I think the 1 million estimate is probably too high. Just because they're dormant doesn't mean they're gone.
