Yes and no. The town I live in has multiple billionaires living in it, and is adjacent to two with even more. I've visited two houses owned by such folks and their answer is what you'd expect: private security guards. Large, well-armed, and very unfriendly until they've verified via radio you're actually supposed to be there. The key is, though, and maybe this is what you're referring to, that these folks don't store wealth on their home PCs. So their threat model is a little different. I'm sure HN readers who follow Bitcoin more closely than I do could think of a better system, but presumably the real Satoshi could hire lawyers to set up a company or trust to hold his bitcoins, sell them over time, and store the proceeds in a more traditional manner. Not especially difficult. And, assuming taxes are paid, it may even be possible to remain anonymous.
