Sorry for the double post, but something hit me a little while ago and I was waiting for a post to say it but nothing came. So yeah.
I'm wondering, what are all you guys in the treaty going to do if a new species is discovered? Or a new government? I really doubt they're going to just adopt one of our currencies outright, so wouldn't this mean your companies would be trading with an illegal business if they did business with any company from that nation, unless they signed the treaty? Also how will you do business with nations that don't sign the treaty at all.
There are like zero upsides to this treaty but a lot of actual and theoretical downsides. There is no real gained security from the treaty, cause a nation has the power to dictate trade laws in their land if they don't sign the treaty, so they can make laws dealing with their specific issues for security purposes.
