Barbara McQuade at USA Today explains quite why the FBI and justice department might be concerned about White House documents being left lying around a Trump residence like Mar-a-Lago. It isn't just a matter of wanting to retain a complete record of Trump's time in office for the sake of it. She writes:

Mishandling classified information is a serious crime because it puts at risk sources and methods of information relating to national security. If the content of the documents were to end up in the wrong hands, the identity of government sources could become known and their lives put at risk. Or our methods of collecting information, such as technological capabilities, could become known, undermining their utility. You can't leave boxes lying around when they contain the kinds of government secrets that can get people killed, even if you're the former president.
