At this point it's beginning to look as though meeting with Jeffrey Epstein was some sort of prerequisite to joining the club.
Maybe the story really is that Epstein met with Thiel.

and if his ill-gotten gains were sufficient he could have started his own private office which is not hard to do at all if you have the money, which then establishes him as a "financier" who would have cover for all sorts of things (nobody cares to look into what you are doing if you run a private office.)
He certainly did financial things for people like help Noam Chomsky move some money around, but again, it's not hard at all to set up to do that. Once you've got a reputation as a "financier", philanthropist, etc. it certainly opens doors for you.
