Chazumi and greenpeace's systems of government are equally flawed and unworkable. At least Chazumi has the sense to recognise that there will be greedy SOBs out for personal power, he just seems to think he can somehow stop it in his system, which is of course bull.
Optimisation would provoke an armed resistance immediately. If that fails, there will be eventually be mass, organised resistance. If you are successful in creating a new race that simply does as it's told, the only way such a system will work, it's not optimisation, it's technocracy, and that's just as flawed.
I'm sorry Chazumi, I sympathise with such a system, but it simply will not work. For a start, there's no room for growth and mutation, which are necessities if the human race is to avoid stagnation and eventual extinction, as such growth and mutation would not be 'optimal.'
