If you have a social life there are people in your circles of varying degrees of trust and interests, and as people change, you want your inner life and history's exposure to them to change as well. I feel like you are treating a complex phenomenon that you can obtain regular feedback from like something that's complete-trust or zero-trust.

There has been a use for exploding messages, and there's a use for deletable messages too, despite the screenshottability by zero-trust parties.
