Self-custody with metal plates and stuff is really nice, but I'm having a hard time believing that the average person would ever do anything like this (or even try to understand why they should). Part of the power of Web3 isn't just that you own the keys, it's also that there's a wide variety of storage options that anyone can choose from, other than in Web2 where everything is set by the respective provider. That, to me, is the real power of Web3: having a choice.
