Why can't we have robotic labour as the foundation for the following? Because such a level of robotics capable of doing all the work for us do not exist? Kinda missed the obvious there didn't you. Why don't we have it? It doesn't exist.
As for a resource based economy: Would you let your employer pay you with plastic? Do you think you should be able to pay for your groceries with iron or zinc? Yeah that's a brilliant idea. Why can't we do it!?
A more decentralized government would be great (no sarcasm). Unfortunately politicians chase power and collect it. And no one is aware or cares enough to ever fight this trend.
As for "An apolitical, completely independent, international, non-profit NGO responsible by a detailed constitution for providing basic resources necessary for ensuring the opportunity for survival and self-actualization of all people," I have to wonder how it would be completely independent when it would be payed for with a gigantic tax rate. How would you ensure that everyone your nanny-NGO provided for was contributing to the system to the best of their ability? The obvious reason why not is who is going to pay for it? I don't have that kind of money. Neither do you.
OGLUs are expensive. Again, who's going to pay for them? People don't work for free. Or for coffee beans, or most any other resource.
