You tell people that value their bitcoin to migrate to new wallets. Bitcoin is self sovereignty and self-ownership. You are responsible for securing your own wallet.

The bitcoin that has been lost doesn't matter, because it's lost. That becomes fair game to whoever can find the computational resources to crack the cryptography of the wallets to get to it. At that point BTC will probably be $500k-$1M in price, and it might just be the driving force behind mainstream adoption of quantum computing.
