Hmm...Good points...
Does it maybe solve this. I’m not sure.
Also one of the problems is (or might be - so there is no fixing of market’s gap right now) that they are controlled by a centralized company right. Having a decentralized storage ALWAYS fixes that problem...you don’t want to have ultra-valued key that is stored in someone’s hands. As I said, Blockchain still remains to be successfully hacked, so it makes it THE safest place where to store such an info for now right?
