I think it’s important to recognize that all self custody solutions have trade offs.

HWWs are great for many people but they come with privacy risks.

HWWs are physical, easily identifiable devices. For those who are nomadic, possession of one quickly doxxes you to people like border guards, hotel maids, girlfriends, etc.

Buy a HWW online? You’re in many databases if you use your address and credit card.

Of course, some HWW have additional security risks (unverified random number generators, software updates, hot connections to potentially compromised computers, etc) that many plebs don’t realize.

Anyway, I consider self custody to be an unsolved problem. We don’t yet have good UX for easy, private, and secure self custody with inheritance.
