Bitcoin self-custody is not for everyone. When Bitcoin is the standard (and it will--as it is the hardest money), the vast majority of people will be using a layer of money built on top of it and will have zero clue that they're operating on Bitcoin rails.
And so to my point, and from now a few years of experience, self-custody is too daunting for most folks, it's not exactly easy either. Different forms of custodians (small federations and whatnot) will emerge over time that will do a better job of keeping people's bitcoin than those individuals are actually willing to do, at a cost. And that's okay, and it's especially better to the current fiat alternatives which is garbage and offers no guarantee except that your purchasing power can't stop eroding.
