You can make up any story you want, everything you said is alleged, and some of it not even said.
Biden STOLE THE INFORMATION FOR DECADES as a senator and VP, kept it insecurely, had more documents involved than Trump, and had no declass abilities or clearance to possess it. Every classified document in his possession was a federal crime for him to personally keep.
Maybe Trump planned to return it in a couple decades too... Maybe it was legally declassified by Trump. And we all watched Smith get appointed illegally, tamper with evidence in staging photos, and blatantly lie. You have no idea what level of classified any of it was because you don't know what it was and Trump WAS THE POTUS with the clearance to possess it.
