Pays to remember that someone who has never heard of a key pair before could well need several hours of research to genuinely understand the concept of a private key and a public key and a signature.

And maybe several days, because many will have to circle back to grab a bunch of underlying concepts in math and computation that they don't have pre-packed.

And maybe years—as in they need to catch up on years of missing context before they have the educational foundation to genuinely (key word) grasp what a key pair is and does.

If you go through nStart and other "normie-friendly" onboarding tools, these tools make some ridiculous assumptions about what the average normie has cognitively pre-loaded.
