No one can force him to work but at the same time he cannot stop anyone else from recreating his work. A brand name doesn't prevent copies, a logo might be trademarked but everything else would be fair game. Cabinets have long since been invented so there's no patent issues and the design of a utilitarian item is not subject to copyright.
