That's what I do. Content that gets deleted is less valuable.

To me, it feels like you want the benefits of using an identity (collecting sats and being known) but without the responsibility (letting people scrutinize what you say and being responsible for your words). To be clear, I don't mean responsibility in the way a government means, but as in reputation. The good thing of sovereign voluntary identities is that if you screw up you can start over with a new one.
