He basically says that storing bitcoin is easy for individuals, but for organizations of diverse type it is difficult and costly. Interesting.
Which to be perfectly honest, is a stupid thing to assert. If you think about it for a minute you'll see that it really is not possible for employees of an organization to get away with stealing the org's bitcoin, any more than they can get away with draining their traditional bank accounts.
If they use multisig, and the bitcoins disappear, the blockchain will show who signed. Organizations aren't so idiotic that they wouldn't bother to record whose keys are whose. They'll see Bob and Mallory signed the 2/3 and stole the funds, Bob and Mallory are arrested. They may say "we were hacked" but they can save it for the judge.
Now, in the case of bitcoin, Bob and Mallory can refuse to cooperate so the org might not get their money back. But I don't see what's tempting about this crime, seems like a dumb thing to do.
