The nearer High Frontier (was The ability to build new land)

You can indeed build very tall buildings on Earth. You can build arcologies. You could, in fact, build arcologies as artificial islands in the ocean. These are all possibilities and I hope we do all of those things.

And space still provides for more room and more resources to build with (especially when you consider how much of the Earth's resources are beneath the crust, in the mantle or the core).
