No I think it is you who are slow to understand what the conversation is even about. I responded to your comment, "If everywhere is fairly dense, less dense areas go for a premium" by saying that you can't make Everywhere dense.

You can't make Everywhere dense in the USA because there are 3.7 million square miles of land that make up the USA. Much of that land does not have humans occupying it. The cities where most of the population stays take up only a small fraction of those millions of square miles.
