It will be interesting to see if one day there’s a mechanism to declare coins lost or abandoned. Or maybe coins that are dormant for too long will be turned over to the state, like abandoned bank accounts.
There will be a lot of coins that will be dormant so long that they are obviously lost. But to try to reclaim them externally would go against everything crypto stands for.
There’s really no way to do that anyway
a fork could require long dormant coins to be re-mined but inevitably some people would lose coins that they intended to use.
