no, not derivatives or similar work, your actual work. without copyright, anything you put out into the world can be taken and republished by anyone with more resources, in larger quantity than you can manage, in wider distribution than you can manage, with no compensation to you. an example of this is pornhub and similar sites, which make money from content lifted straight from independent producers. large distributors have the leverage to keep their content off of the sites and use them as advertising platforms instead, but overwhelmingly, content purchased from smaller paysites and portals is uploaded without consent, license or remuneration from producers who lack resources to fight.
