Nobody gives someone that much of a gift for nothing. I do suspect he was blackmailing rich people all over the world
After everything I have read about Epstein since his death that is exactly what I surmised. He was running a high end extortion racket. He would lure in rich people into his trap. First at the Manhattan townhouse, then the Palm Beach house, the NM ranch and finally the Virgin Island.
He may have been sponsored by our government or even the Mosad due to his girlfriends fathers connections. Probably not directly, more like a private contractor. We will never know. I do not believe he is alive because dead men tell no tales. He was expendable.
