Curation should be optional. I've already written about this a lot.

Long story short, curators aren't curating anything. The frontend is responsible for displaying all content to the user. Therefore, there exists a link from the frontend (curation) to the backend consensus layer that absolutely should be severed.

Frontends of Steem should have no effect on backend consensus. It's totally backwards to force "curation" on people.
