This is helpful, his explanation of the keys and "why" is really simple.

The way I've been explaining it to people leans way to heavy into the censorship resistance, a lot of the people I'm trying to bring to Nostr don't really care about getting censored, when Facebook takes down your memes it's a badge of honour type shit they got nothing actually important to say, so I'm going to re-watch this a few times, try to change the way I'm explaining it, why using keys is better to an email and password.
