I don't think most people delete posts because they are low-value. I believe most people delete posts when they realize they don't want their name to be associated with them. Short of comments with sensitive and/or personal information in their content, I do see value in preventing comment deletion. That is, assuming that you can disassociate your name from it. I embrace edits, but I do think it's important to allow full access to edit history.
