The interesting thing to me here was the different kinds of attitudes people have and the weight they attribute to different concerns. Other people are filled with trepidation. I wrote a message to some right-anarchist mailing lists on the theme that international trade treaties aren't only about free trade. Maybe I'll quote a copy of my mailing list post here. Some of my friends who are not particularly sympathetic to libertarianism but do have some understanding of libertarian ideas suggested that we need to look beyond the titles of treaties to see what provisions they actually contain.
Some treaties do give regulatory power to treaty organizations instead of governments.
But that doesn't help me when I want to sell some item and the Customs agent at the border considers it subject to a duty. We did laundry.
