I’m not sure I understand this statement. Global economic integration is merely trade, it doesn’t stop people from making laws governing their own lands. Likewise, making local laws (unless they’re specifically putting up trade barriers) doesn’t really interfere with global trade.

I guess you could argue that in choosing to enter into greater global economic integration, a country is losing some autonomy (national sovereignty) as it will be required to remove trade barriers, etc, in order to join. But if that decision is made by a democratically elected government, then I really fail to see how it’s antidemocratic or reducing sovereignty. You could make the same argument about signing pretty much any other international treaty. But the purpose of international treaties (as with domestic laws) is that they’re mutually beneficial.
