It's rather hard to say, isn't it? Nobody ever tried objectivism as the central theme of government, and so, while there is validity in the conjecture, we're a bit short of factual data.

What's interesting is that, bottom line, people do what they believe will benefit themselves first, and others later. Objectivism merely chooses to acknowledge that fact, rather than hide it behind high-falutin' words and phony ideals.

We don't know for a fact whether such a system will work or not. I suspect that the people involved in designing such a system would make all the difference - France is essentially socialist, and so is North Korea, but we would not call them equivalent, would we?

It doesn't matter. I rather like objectivism as a philosophy because it relies on the individual. It won't ever be a system of government, as far as I can tell, because of objections like yours; but the fact that it could be misapplied is not a valid argument against it. Anything can be misused.
