You are not wrong, but a more accurate analogy is like switching from Windows/Mac to Ubuntu. 

I don't see it difficult either. I think it's the simplest process ever. what comes after the signup is the unclear part. 

Relays? why do I want those?
I can't recover my account?
If someone hacked my account I can't message customer support?
etc. etc. 

 Ah yeah, for sure. Just talking  about the initial steps.  I think relays should just be hidden and let them learn about account migration on their own when they need to 😂 

 And let's not get into note edits and deletion.

That's onboarding, creating a key pair is not onboarding.

all the people I helped joined nostr created a key pair and never posted a single note. lol
