Quick reminder, in the context of "Trump wanted to keep things for vanity, not to sell government secrets", we still don't know what the classified documents actually included. The ultra high level mega classified stuff could be things like a personal letter from a foreign leader or the details of how Trump was transported to and from a major event (which is obviously a highly classified document beforehand but utterly harmless now). There may have been literally nothing consequential to national security in Mar-a-Lago.
