I can not answer that, here are some thoughts.
The records are government records, so the government has a right to them, probably the originals. If they are electronic records, or printouts, then they are already copies, especially if the government has the original electronic documents.
I think the question really is: Can a former President use knowledge he obtained as POTUS to further political or financial gains? Therein must be a fine line and a high bar of proof. Selling those documents would seem dangerous to allow, like including it in emails to get foreign contracts or cash. However, using that knowledge for political purposes would force you to arrest every POTUS in history. Sudden windfall of post POTUS cash, with people accessing the documents, would be immoral, and may be prosecutable. I think that might be a high burden of proof as well.
When the government is supposed to pack the POTUS records, and we the taxpayers pay an agency to do so, if documents that are vital to national security are released, blame should go to the government. If a POTUS takes records of government illegal activity, that’s perfectly legal IMHO, and potentially necessary.
What I am saying, is that the POTUS represents a special position, and outside of selling records or using them for financial gain, it’s legal, IMHO. Selling information, or using it to coerce foreign or domestic governments, probably not legal but would be a high bar to prove. Certainly, if the records demonstrate illegal US Government activity or plans, that is something that should be kept and released at discretion of the former POTUS.
Who knows, they might keep it all in a sock drawer…….
I think if I were one of the Grand Jurors and I found out that Jack “Dog Feces” Smith had not provided the Presidential Records Act and the Judicial Watch / Clinton Case, I would be approaching the Judge overseeing the Grand Jury to have the prosecutor sanctioned and the indictment thrown out.
