This is part of the reason why I see value in something like BlockOne ID (by Thomson-Reuters)[0].
I think it's a noble pursuit (what the US Digital Service is trying to do here[1]), making the internet easier and more accessible for people. For many people, involving themselves in the constant updates of what service is secure versus what service is not and "I have to sign up for a different email now to log in to the thing I used to log in to" is a nightmare -- and this isn't restricted to the elderly.
I think it's noble, because I really think it shouldn't be arcane. To a lot of people the nuances still are, unfortunately.
But a service that translates blockchain addresses into WWW accounts and back has some value, no? Couldn't it do a better job of this? I'd love to know if anybody has any more insight or thoughts. I haven't dug too deeply yet, but it keeps coming back to me. Perhaps BlockOne ID isn't the ultimate execution, but maybe one could be developed. Something that requires one sign up, and can be used as ubiquitously as you like.

[1] For instance, with Canadian Government services I require an account for every single service, often with different password and username requirements and age limits. I understand why, but for somebody who doesn't spend so much of their career(s) on and around and familiar with computers and how they work, it could be prohibitive.
