The gold wasn't to bribe other countries (though I do remember something dealing with the underwater hardlines), it served several purposes, including giving Epiphyte II hard assets--thus preventing The Dentist from recouping the entirety of the corporation in litigation for corporate negligence, and/or reducing the equity share he would receive if he did win in court [I can't remember])--and also creating a solid basis for digital currency without requiring them to deal with some of the shadier sorts in the earlier Kinakutan meeting, and finally there was some mention of along the theme of holocaust prevention, since the money came from the blood of others to begin with.
