The way I see it, this isn't something that most of us need to worry about as long as we aren't going around bragging about how much crypto we have.  I'm not saying that that's what this guy was doing; I think he was targetted because he was a broker or something which made it public knowledge that he had crypto-assets.  To the criminals, he was likely seen no differently than anyone else who had a stash of valuables in his house.  The only thing that made this story remarkable was the fact that it involved crypto instead of cash, gold, jewelry, corporate secrets or any other easily carried stores of wealth.
