I don't really make that distinction, I think it's harmful to have E2E as optional, and only use platforms than have either mandatory E2E encryption (Signal, WhatsApp), or no E2E encryption (SMS, email).
If you have an in-person conversation with me in confidence, that doesn't grant you any additional powers to make me forget details of the conversation.

What if I have a very good memory, and follow conversations by writing up their details in personal memos that you can't delete? (e.g. Comey's contemporary memos of conversations he had with Trump.)

The problem for you is that I'm not going to agree to that - if you won't use Signal, I'm going to force a downgrade to SMS or email, and then you get even worse security and privacy.
If you want to have a conversation that can't be recorded in an automated way, you basically need to meet in a sauna.

Or we will set up e2e encrypted telegram. Or not talk.

You saying that you remember I said something, even took a screenshot vs you can prove I said something, is a big difference.
If I am doing a snowden, I might go to a sauna. If I am planning to overthrow my boss, I think e2e telegram is okay. Because I can delete the conversation it might even be preferable to signal.
Sorry, I just can't agree with your take. You're fundamentally trying to use technology to restrict rather than enable use cases, and doing so in ways that aren't actually robust to your use cases and threat models.
