This is a very interesting topic, with a hard shell to crack.
Looking at it closely, in the aspect of technology evolving, maybe a technology with such solution may come up in the future, and this will be good with its own forms. With a technology of this nature, the possibility of getting into any wallet might and will be possible. Cause if a lost coin can be found without its key, then the difficulties of accessing any wallet with bitcoins won't be far from this technology. This also will make bitcoin to have another step in its own technology, so as to protect the holders and users of bitcoin from losing their coins.
