You've got to clear out the solar system anyway, so you use all the solar planets in the construction. That gives you a shell of, say, chrome steel a few yards thick. Now you put gravity generators all over the shell. You'd have a surface area a billion times as big as the Earth's surface. A trillion people could wander all their lives without ever meeting one another."
