While I appreciate the point you're making, and don't completely disagree, I think you make a faulty assumption about our collective ability to find a suitable sovereign and that person's ability to resist the very same forces that lead to the inevitablity of corporate overreach. Having a single person with that much power was the core reason historic Americans revolted from the crown, and I don't think they were wrong

Again, I appreciate your statement of the problem. But I'm scared of your hypothetical solution.
