We had this debate years ago on the Steemit blockchain... There's what I believe to be a very simple solution.

Initially, Steemit allowed editing for typos and second thoughts for a brief span (~10 minutes?) after posting.

As an author, I wanted complete control in perpetuity over my work, and fought for that outcome tirelessly.

The final solution?🤔

Versioning. Each new edit is saved as a serialized version of the original post. Anyone seeking the "truth" about the ugly, typo-ridden original is welcome to dig back to ground zero, as nothing is deleted, while serious authors can fix typos they may have missed years later.😃
