   then we'd see a distortion free economy

That is either incredibly optimistic, or incredibly naive. Perhaps both. To the degree that Rand's thoughts can be made consistent in this area, they touch on many areas of economic complexity that nobody has a very good idea how to understand & model, let alone control.

Right. No one man (or small group of men) can understand, model, or control many areas of society. (Depends specifically what you have in mind here.)

But it's not incumbent on Rand to plan these areas. (Not sure if you're implying that it is.) Free market price signals do the majority of the heavy lifting, in resource allocation, broadly speaking.

To the GP, I would stipulate "state distortion free". ("State", as in "by force".)

That's ideology, not science. So still being optimistic.
