Only governments that meet certain criteria please!
There are some advantages to goverments having the final say IF...
They are democratic
Not Jerrymandered constituencies
Not under the control of business - big, small, home or foreign
Ones that provide for their citizens - free universal healthcare, education welfare etc
Ones that do not think their national laws are global
Ones that follow international law
International court of human rights
and so on.
No government that does not fill these criteria as a basic minimum should have any say in any international bodies.
