He's always the president once he was a President, just not in an everyday official capacity or role like an active one is,
False, once he leaves office he is no longer President. There is only one President in the Oval Office at any one time. Referring to him as "Mr. President" is ceremonial only.
but certain rights he had during his official capacity, well they still extend beyond that official capacity. Such as the right to have a lifetime secret service detail,
That isn't a "right", that is authorized by Congress. Congress can remove it. (Not that I think they will.)
and also his right to retain and hold his declassified documents that are to be stored in a "secure" location of his choosing.
This is false, Presidential Records are the property of the United State government and by law must be turned over to the National Archives and Records Administration. ** THEY ** decide on the storage location.
If the President establishes a non-profit "Presidential Library", the non-profit manages the facilities. However the NARA ** STILL ** retains ownership and responsibility for the documents and will coordinate with the non-profit for public access and displays. Basically the organization manages the building, the NARA manages the Presidential Records.
The president and his records during his tenure are his and the governments property for summoning purposes if need be,
Presidential Records during his term of office are not "his", they are government property. During his term of office he is administering them as part of his official duties. Once he leaves office, by law, Presidential Records must be turned over to the NARA.
so unless they have a classified status that wouldn't allow them to be removed from a government secure location that it monitors and/or views in scifs, then Trump has every right to the records or documents that he possesses.
The documents at the center of FPOTUS'#45's legal troubles in the MAL case ** ARE ** classified documents that were removed from the White House (secure location) and sent to his social club (unsecure location).
So, no. He does not have a right to unclassified Presidential Records as they are not is. And as a separate issue, he also does not have a right to classified documents at his social club, once he left office and the government was no longer maintaining security at the facility. (There was a temporary SCIF installed at MAL during his term, but that was removed when he left office.)

Now go ahead and flag this with "disagree" or "fake news" because the truth is something to be ignored.
