Lightning using mSats doesn’t solve the problem of the main chain needing a solution of dust transaction being personal fortunes - in the problem you stated of having so many lost coins

Nope, but it might make life easier today for people in third world countries trying to do circular economies in bitcoin.
Was thinking more about this.
If the transactions that fund Lightning can’t end up being accepted by miners on the main chain then the whole thing falls apart.
In the future you describe - I think we both agree that mSats will be valuable - likely enough to pay for blockspace - such that the dust limits will need to be rewritten across every transaction that’s still enforceable.
Some group of great Bitcoiners will figure it out and will it through.
