Apart from the awkward misunderstanding of the word "universal", there are other issues with this proposal. For one, having a high IQ is neither necessary nor sufficient for making a major contribution to society. For a variety of reasons, most people with very high IQs never do anything important with it (in the sense of an invention, a company, a movement, a masterpiece, etc), and it's not because they lack a guaranteed income. If I had to guess, I'd say it's because IQ, vision, and motivation are three different qualities which are, at best, weakly correlated.

If you want to make your country better, make it easier for people with good ideas to get the resources to pursue them. For starters, make it easier to get grants. There are already projects trying to do this, but having 100x the resources wouldn't hurt.
