I thought so. Something like that would have trouble operating effectively in a world like mine, but then, the human government of my time is rather ineffective itself considering how scattered we all are.

[Trying to govern people on one planet is hard enough. Trying to install a single overarching human government when trillions of humans are spread across the galaxy? Just about impossible.]

There are probably still places it could work, but most planets don't keep to themselves, for one reason or another.
