You're supposed to store $10M in BTC on the blockchain, which - after all - records ownership of every bitcoin ever mined. And keep access to it in a paper wallet; control of those $10M lies in access to a private key, so if you keep the key secret, nobody can access them (like with Satoshi's $40B or so in Bitcoin).
That people don't seem to want to do this is perhaps a lesson in human nature that crypto-anarchists and other aficionados of "trustless completely-distributed systems" should perhaps heed. This same dynamic comes up over and over again, from open-source to the Internet to P2P and now to cryptocurrency.
