Government won't allow him to go to a prison. It would be a liability for nation security.
If he died in Jail by 'any' means. Even old age. It would martyr him for the crazies for years.
Foreign Entities would go crazy for the chance to Epstein him. It would de-stabilize the US for a decades, as no one would believe any facts and it would be conspiracy city.
He'll get house arrest, and go full blown 24/7 bitching about it.
