You think fiat money is never lost, there are millions lost every year and you cant fix that. As long as there is human factor present, it will always happen and you have to accept it.
fiat/cash being lost is because it is designed that way. paper is not exactly the most resilient of materials on the planet. but a token that is based on unbreakable code and cryptography should not be lost ever. when you release something and put a huge value on it, you should make damn sure it has no bugs.
it would be like printing money with a terrible mold that prints each note different than the last!
