No one is disputing that a better system cannot be devised. This is true for many problems in the world. If you could start from the zero state, you can do it much better.

So let me say this: _coming up with the ideal system is not hard_. But how will you transition the world from its current state to this ideal state? Consider that the metric system (or SI), which is much better than the US system of measures, has still not been adopted in the US. Why? Because the problem of transitioning between systems is called politics.
